MAI immergere nei liquidiQuesto prodotto può contenere una sostanza chimica nota allo stato della California per provocare cancro, difetti alla nascita o altri danni riproduttivi.3. Come questo termometro auricolare misura la temperaturaQuesto termometro misura l'energia infrarossa irradiata dal timpano e dal tessuto circostante. Questa energia viene raccolta attraverso l'obiettivo e convertita in un val-ore di temperatura. La lettura misurata ottenuta direttamente dal timpano (membrana timpanica) può garantire la temperatura dell'orecchio più precisa.Le misurazioni prelevate dal tessuto circostante del condotto uditivo generano letture più basse e possono provocare diagnosi errate di febbre.Per evitare una misurazione imprecisa:Questo termometro è stato testato clinicamente e dimostrato di essere sicuro e accurato quando utilizzato in conformità con il suo manuale di istruzioni operative.Accendere il termometro premendo il pulsante ON / OFF.Dopo aver sentito un segnale acustico (e l'icona della scala della temperaturalampeggia), raddrizzare il condotto uditivo tirando delicatamente la parte cen-trale dell'orecchio verso l'alto e verso l'alto.Posizionare saldamente la sonda nel condotto uditivo, premere il pulsante START e mantenere la sonda nell'orecchio finché il termometro emette un seg-nale acustico per identificare il completamento della misurazione.1. 2.3.Se lo strumento non verrà utilizzato per un periodo prolungato, le batterie dovrebbero essere rimosseAssicurarsi che i bambini non usino lo strumento senza sorveglianza; alcuneparti sono abbastanza piccole da essere ingoiate4. Display e simboli di controlloTutti i segmenti visualizzati: Premere il pulsante ON / OFF per accendere l'unità, tutti i segmenti verranno visualizzati per 2 secondi.Memoria: l'ultima lettura verrà visualizzata automaticamente sul display per 2secondi.Pronto per la misurazione:l'unità è pronta per la misurazione, l'icona ° F o ° C continuerà a lampeggiare.Misurazione completata:la lettura verrà visualizzata sul display con l'icona ° F o ° C lampeggiante, l'unità è di nuovo pronta per la misurazione successiva.Indicazione della temperatura fuori dall'orecchio:Un'icona con le orec-chie incrociate visualizzata sul display se la lettura non rientra nell'intervallo 89,6 ~ 108,0 ° F (32,0 ~ 42,2 ° C).Indicazione di batteria scarica: quando l'unità è accesa, l'icona della batte-ria continuerà a lampeggiare per ricordare all'utente di sostituire la batteria.5. Istruzioni per l'usoPremere il pulsante ON / OFF. Il display è attivato per mostrare tutti i segmentiper 2 secondi.L'ultima lettura della misurazione verrà visualizzata automaticamente sul displayper 2 secondi con l'icona M.Quando l'icona ° F o ° C lampeggia, viene emesso un segnale acustico e il ter-mometro è pronto per la misurazione.Raddrizzare il condotto uditivo tirando l'orecchio verso l'alto e indietro per dareuna visione chiara del timpano.• Per i bambini di età inferiore a 1 anno:tirare indietro l'orecchio.• Bambini di età compresa tra 1 anno e adulto:tirare l'orecchio in alto e indietro.Vedi anche le brevi istruzioni a pagina 5.Mentre si tira delicatamente l'orecchio, inserire la sonda nel canale uditivo e pre-mere il pulsante START. Rilascia il pulsante e attendi il segnale acustico. Questa èl'indicazione che conferma la fine della misurazione.Rimuovere il termometro dal condotto uditivo. Il display mostra la temperatura misurata.1.2.3.4.5.6.NOTA: al fine di garantire letture accurate, attendere almeno 30 sec-ondi dopo 3-5 misurazioni continue. L'accumulo di cerume sulla sonda può causare letture della temperatura meno accurate o in-fezioni incrociate tra gli utenti. Pertanto, è essenziale utilizzare una sonda pulita prima di ogni misurazione. Per la pulizia, seguire le istruzioni nella sezione Pulizia e disinfezione. Dopo aver pulito la sonda con alcool, è necessario attendere 5 minuti prima di eseguirela misurazione successiva, in modo da consentire al termometro di raggiungere la temperatura di riferimento operativa.10 toni brevi suonano quando la temperatura è superiore a 99,5 ° F (37,5 ° C)per avvertire il paziente che potrebbe avere la febbre.Per un bambino, è meglio che il bambino penda piatto con la testa di lato inmodo che l'orecchio sia rivolto verso l'alto. Per un bambino più grande o unadulto, è meglio stare dietro e leggermente al lato del paziente.Prendi sempre la temperatura nello stesso orecchio, poiché le letture della tem-peratura potrebbero essere diverse dall'orecchio destro e dall'orecchio sinistro.Attendere alcuni minuti per prendere la temperatura dell'orecchio dopo aver dor-mito.Nelle seguenti situazioni si consiglia di prendere tre temperature nello stesso orecchio e quella più alta presa come la lettura:1. 2.3.Neonati nei primi 100 giorni.Bambini sotto i tre anni con un sistema immunitario compromesso e per i quali la presenza o l'assenza di febbre è critica.Quando l'utente sta imparando come utilizzare il termometro per la prima volta fino a quando non ha familiarizzato con lo strumento e ottiene letture coerenti.6. Fahrenheit a Celsius commutabileQuesto termometro può visualizzare le misurazioni della temperatura in gradi Fahrenheit o Celsius. Per cambiare la visualizzazione tra ° F e ° C, è sufficiente spegnere l'unità, tenere premuto il pulsante START per 5 secondi. Quando si smette di premere il pulsante START dopo 5 secondi, la scala di misurazione corrente (icona ° F o ° C) lampeggerà sul display. Passa dalla scala di misurazione tra ° F e ° C premendo di nuovo il pulsante START.Una volta selezionata la scala di mis-urazione, attendere 5 secondi e l'unità entrerà automaticamente in modalità di mis-urazione pronta per la misurazione.7. Come richiamare 12 letture in modo memoriaQuesto termometro può richiamare le ultime 12 letture.Modalità memoria:premere il pulsante START per accedere alla modalità di memoria quando l'alimentazione è spenta. L'icona della memoria M lampeggia.Lettura 1 - l'ultima lettura: premere e rilasciare il pulsante START per richia-mare l'ultima lettura. Visualizza 1along con l'icona della memoria.Lettura 12 - lettura in successione: Premere e rilasciare il pulsante START consecutivamente per richiamare le letture in successione, fino alle ultime 12 let-ture. Premendo e rilasciando il pulsante START dopo che le ultime 12 letturesono state richiamate, si riprenderà la sequenza sopra riportata dalla lettura 1.8.

Scepter™ 2.0 Cell Counter Precise, handheld cell countingThe life science business of Merck KGaA,Darmstadt, Germany operates as/scepterupgrade Precise, handheld cell countingScepter™ 2.0 cell counters mark the next generation in Scepter™ technology, highlighted by:Compatibility with More Cell TypesIncreased Cell Concentration RangePowerful Software for Complex, Effortless Cell AnalysisScepter™ 2.0 Cell Counter• Recommended based on size • Customer Validated• MilliporeSigma Validated“At last, an alternative to lining up for the Coulter Counter ®, and far easier than sweating over fragile hemocytometers.”Amy A. Caudy is a Lewis-Sigler Fellow at Princeton University’s Lewis-Sigler Institute for Integrative GenomicsThe Scientist , Dec. 2010. Top Ten Innovations of 2010.The power of precisionTrust Scepter™ devices with your most valuable samples to get reproducible and reliable counts. The reliability of Scepter™ cell counters is particularly apparent with smallercell types. Because the Scepter™ cell counter measures volume using the Coulter Principle, it can quantify cells based on size and will discriminate larger cells from smaller debris, unlike vision-based techniques, which rely on object recognition software and cannot reliably detect small cells.Scepter™ sensor technologyCompatible with 60 μm and 40 μm sensors, theScepter™ 2.0 cell counter can meet even more of your cell- and particle-counting needs. Use the 60 μm sensor for particles between 6 and 36 μm. Use the 40 μm sensor for particles between 3 and 17 μm.• Precise volumes are drawn into the Scepter™ sensor.• As cells flow through the aperture in the sensor, resistance increases. This increase in resistance causes a subsequent increase in voltage.• Voltage changes are recorded as spikes with each passing cell.• Spikes of the same size are bucketed into a histogram and counted. This histogram gives you quantitative data on cell morphology that can be used to examine the quality and health of your cell culture.Particles are detected by Ohm’s Law V=IR (V=voltage, I=current, and R=resistance).Table 1.Cell types validated with the Scepter™ cell counter and the recommended Scepter™ sensor.Cell Type Measuredsize (μm)40 μm sensor 60 μm sensorMeg-0116-17•MG-6315-17•Mouse ES Cell5-13••Mesenchymal Stem Cell 15-16•MRC-5•NCI-H14610-13•NIH 3T315•NTERA2, clone D113••OK 17-18•PBMCs 7-12•PC129-13•Primary Astrocytes 7•Primary Neuronal Cell •Raji 12-15••Ramos11-12••Rat Dorsal Root Ganglion Cells 7•Rat Whole Blood 4.6•Red Blood Cells 5-7•Rat Neural Stem Cell 11-13•RAW 264.712-15•RBL 11-13••RIN-mF513-14•SF913•SH-SY5Y 12•Sk-Br-315-20•SK-MEL-2817-19•SK-N-MC 14-15•SK-N-SH 14-15•Splenocytes 7-9•SW-48015•SW-62013-14••T8414-18•T98G 17•TF-113-14••U25116-20•U2OS 16-19•U26612•U87-HumanGlioblastoma cell line 12-14•U93711-13••WI-3812-15•Y7913-14•Yeast- Pichia Pastoris 5•Yeast- S.cerevisiae 6•Cell Type Measuredsize (μm)40 μm sensor 60 μm sensor2102 Ep 15-19•454 beads •A17215•A25314-18•A37516•A43115-17•A549•Algae (various)7-9•B3513-16••B Cells6-11•C2C1212••C30512-14••C612-13•CA4610-12••Caco-217•CHO 14-17•COS-112••Cos-715•D28312•Daudi 10-12••DU-14515-17•Epithelia 14-15•HCT-11610••HEK29311-15•HeLa 12-14•HepG212•HFF 18-20•Hs2714••HT-108014-16•HT-2911•HUH7- Hepatoma line •Human ES Cells 9-12•HUVEC 14-15•IMR-3212-14••IMR-9015••Jurkat 13•K56222•KB 14•KG-110-13••L614-16•LNCaP15-16•Luminex ® beads 5-6•MCF715-17•MDCK13-15•Scepter™ cell counterHemocytometer= Average % CV= Coulter counter % CVVision-based counter1234567Figure 2.The average percent coefficient of variation (CV) for each counting method shown was calculated using cell concentration measurementsat 50,000 cells/mL samples of 19 different cell lines.

MDMA231 cells (A) and NIH 3T3 cells (B) were treated with camptothecin 24 hours prior to analysis.“Cell counting is normally a very tedious process and usually only provides minimal information on the cell population. This instrument, which is only slightly larger than an automatic pipette, allows you to count cells in your tissue-culture hood, simplifies the procedure, and provides much useful data, such as the fraction of intact cells.”H. Steven Wiley is a lead biologist at the Environmental Molecular Sciences Laboratory at the Pacific Northwest National LaboratoryThe Scientist , Dec. 2010. Top Ten Innovations of 2010.Scepter™ 2.0 cell counter for counting heterogeneous cell populationsCount blood cells and other cells with small diameters with the highest precision. Biological samples such as primary isolates or cultured cells are often heterogeneous mixtures of cells that differ by type and/or function. Such differences in cellularattributes are most commonly determined by multicolor fluorescent antibody detection of cell type specific surface marker(s) using flow cytometry. Notably,in addition to variations in protein expression, many cell types and physiological states are also uniquely distinguishable on the basis of size alone. The ability to identify population subsets on the basis ofphenotypic differences and further determine their relative frequencies (and concentrations) is critical to many aspects of research.Scepter™ 2.0 cell counter for cell healthInstantly gauge the health of your cell cultures without even leaving the culturehood. Because the Scepter™ cell counter displays high-resolution histograms of entire cell populations, you can differentiate live cells from dead cells and debris by simply gating on the histogram peak corresponding to larger-diameter cells. No staining is required! The resulting calculation for % viable cells agrees with viability calculations obtained using flow cytometry (ViaCount ® reagent) and Trypan blue staining/hemocytometry (shown here with MDMA231 and NIH 3T3 cells).% C o e ffic i e n t o f V a r i a t i o n (%C V )(40 µm sensor)Vision-based Counter Counting MethodPBMCsAverage % CV Z2 Coulter Counter C o u n tC o u n tForward ScatterFlow CytometryPlot PO3, ungatedScepter™ (40 µm)Current AcquisitionDiameter (µm)100200300400500600700800900100001000200030004000500060005.6 µm Polystyrene MILLIPLEX ® Antibody-Conjugated MicrospheresC o u n tDiameter (µm)1,500,000500,000250,000125,00050,000750,0000.0E+00M e a s u r e d C e l l C o n c e n t r a t i o n (c e l l s /m L )Theoretical Cell Concentration (cells/mL)4.0E+058.0E+051.2E+061.6E+06Theoretical Cell ConcentrationZ2 Coulter Counter Scepter™ - 40 µm SensorsScepter™ 2.0 │ Precise, handheld cell countingScepter™ 2.0 cell counter for countingheterogeneous cell populations (continued)Distinguishing lymphocytes from monocytes in freshly isolated PBMCs . The assessment of immune profiles of the various immune cell subsets can help identify molecular signatures that may facilitate research. The Scepter™ cell counter, when used in combination withScepter™ Software Pro, provides a tool for rapid determination of lymphocyte and monocyte concentrations as well as the relative frequency of these cell types in PBMC isolates.Figure 4.The Scepter™ 2.0 cell counter counts PBMCs with greater precision than other counting methods, as reflected by low coefficients of variation. % CVs were calculated using average cell counts of four replicate samples.Figure 6.Scepter™ Software Pro displays imported size distribution histograms as either a single sample histogram or as overlaid histograms for multiple samples.

Accurate determination of bead counts at the onset of each assay allows for standardization of bead concentrations acrossmultiple samples and minimizes errors and variation in downstream results. The Scepter™ cell counter is well suited for precise counting for beads of numerous types and can improve reproducibility of bead-based assays, such as immunoprecipitation and multiplexed detection.Scepter™ devices can facilitate yeastcell counting for brewing and wine industriesIntroduction of a consistent yeast cell concentration is required for successful beer and wine fermentation as well as to maintain batch-to-batch reproducibility and ensures consistent fermentation over many cycles. Scepter™ cell counter can be used to monitor yeast size and concentration by yielding interpretable histograms that could be gated to provide this depth of information.Ordering InformationDownloadable Scepter™ Software 1O-Rings2Scepter™ Test Beads 1PHCCBEADS Scepter™ USB Cable 1PHCCCABLE Scepter™ Sensors, 60 μm50PHCC60050500PHCC60500Scepter™ Sensors, 40 μm 50PHCC40050500PHCC40500Universal Power Adapter1PHCCP0WER Scepter™ O-Ring Kit (includes 2 O-rings and 1 filter cover)1PHCC0CLIP Table 2.Lymphocyte and monocyte subset frequencies from three individual PBMC samples.

按《医疗器械分类目录》，根据涂层不同，其管理类别也不同。

润滑涂层导尿管管理类别为Ⅱ类，银盐和抗菌成分等涂层导尿管管理类别为Ⅲ类。

随着临床上导尿管的应用日益广泛，由导尿管引起的导尿管相关尿路感染及损伤日益得到重视，如细菌定植、抗生素耐药性、慢性感染、肾脏和膀胱损伤、肾结石、膀胱假息肉、败血症、尿道损伤等[1]。

由于导尿管的原材料天然乳胶中含有对人体致敏性蛋白、生产工艺控制不严、添加剂或助剂使用比例不正确易导致生物相容性尤其是细胞毒性试验不符合要求。

Your Quality, Our Assurance Flow-Through Cell Dissolution Tester Ophthalmic SuspensionsMedical DevicesNanoparticlesIVIVC StudiesInjectablesGranules2Flow-Through Cell Dissolution Tester (USP Apparatus 4)Flow-Through cell dissolution tester is widely recommended for poorly soluble, modified release and extended release dosage forms. With the evolution of new drug delivery platforms, USP apparatus 4 is best recommended for studying the dissolution profile of solid, liquid, oral, non-oral dosage forms and other medical devices such as stents, implants etc. As this apparatus offers highly flexible configurations, ability to work in variety of solubility conditions, different types of cells and positioning of the dosage form, hydrodynamics, sink conditions and flow rates, USP apparatus 4 will continue to evolve to meet the changing needs of today’s dissolution and drug release testing.The USP apparatus 4 comprises of a media reservoir to hold the dissolution media, a pump that forces the media upwards through a vertically positioned flow-through cell that holds the dosage form and a water bath to maintain the cell temperature.The test sample is placed in a vertically positioned flow-through cell through which the media is pumped at a desired flow rate and temperature. The eluate is filtered at top of the cell and is then collected either manually or by a sample collector. The samples are further analyzed using suitable analytical techniques to calculate the percent drug release.The pump unit is responsible for ensuring the most critical parameter of USP apparatus 4 i.e 1. 2. The flow rate must be constant throughout the test, even in cases of back pressure created by the filters. . The USP recommends the optimum 0media temperature should be 37C.Flow rate of the media Temperature ± 0.5 as per USPThe USP regulation recommends that the flow profile should be sinusoidal with pulsation of 120 ± 10 pulses/min ŸUSP apparatus 4 is the ideal choice for poorly soluble drugsŸUSP apparatus 4 is the best method of choice for large media volume dissolution, in order to achieve infinite sink condition ŸFor IVIVC studies, automated media changeovers can be easily achieved for solid as well liquid dosage forms ŸFlow rates can be easily changed to allow ‘accelerated’ test studies ŸMany challenges such as tablet floating, sticking etc. are eliminatedMethodologySystem Specifications as per USP RecommendationSystem ComponentsWhy choose USP Apparatus 4?Heat ExchangerCoilPiston PumpSampleCollectorMedia SelectorMediaReserviorsWaste1234Flow Through Cell Open LoopoCDifferentialtdmC(t) =edtQ((Although USP apparatus 1, 2 and 3 can be used for studying the dissolution profile of poorly soluble drugs, but they fail to offer the optimal sink conditions required. Whereas, USP apparatus 4h as a lways b een l inked t o "optimal s ink c onditions" a s i t o ffers t he f lexibility i n t erms of media volume required. In an "open loop" configuration, there is a continuous flow of fresh media across the dosage form and hence, the total media volume used can be infinite. This means, that the influence of poor sink conditions on the test can be avoided by using larger volumes of media without the need for solubilizing agents. Samples can be collected as a fraction over a timed interval and analyzed using suitable analytical technique. The total amount of media passing through the dosage form is determined by the flow rate. In an open loop configuration, results are calculated as a differential curve or rate of drug release over the time.In an open loop configuration, EFD-07 can be integrated with a sample collector with splitter that enables sample collection for 14 sampling intervals (21 optional) with 75 mL of sample collection volume. Sample collector with splitter, automatically splits the sample volume into collection and waste depending upon the sample volume required.Media Selector Automated media changeover :Unlike the USP apparatus 1 and 2 involving media changeovers, where physical removal of the dosage and change to a new media is cumbersome and tedious, USP apparatus 4-open loop configuration facilitates easy media changeover at predefined time intervals. The flow-through method is the only method that allows for a media changeovers of suspensions and powders. This feature is useful while performing IVIVC studies, where the dosage form naturally passes through different pH of the digestive tract within sink conditions. It is also useful for enteric coated products, modified and extended release drug products. Using EFD-07 media selector, 4 different media can be automatically drawn from different sources at predetermined intervals.Sample Collector with SplitterTMD’light technologyfor audio and visual indication of instrumentstatus from anywhere in the laboratoryMovement of arm to :Sample positionWaste tray / home positionPower onNeedle diving up / downCommunication with dissolution testerError due to :Absence of waste trayAbsence of sample collector traySample collector hood ajarCompletely covered to prevent contamination and air drafts which causeexcess evaporation of the collected samplesOpen Loop Configuration34oC Cumulativedm C (t) =e V htThe closed loop configuration of USP apparatus 4 is similar to USP apparatus 1 and 2 where a fixed volume of media is recirculated through the dosage form. Samples can be withdrawn from the media reservoir at predetermined time intervals either manually or by a syringe system. The samples can be analyzed using suitable analytical technique. In case of closed loop, result of percent drug release dissolved is expressed as a cumulative curve. Closed loop configuration is ideal for dosage forms where solubility and sink conditions are optimal in a limited media volume range from 40 mL to 4 L. For low dose formulations such as drug eluting stents, implants, coated medical devices, injectable and microspheres; closed loop configuration has been utilized to fulfill lower media volume testing. The problems such as tablet sticking, floating, coning or dead zones seen in USP 1 and 2 as well as sampling issues and sample introduction effects are eliminated using the USP apparatus 4.Off-line sample collection for the closed loop configuration is available with EFD-07 connected to a sample collector . Syringes pull the desired volume from the media reservoir and dispense them either into glass tubes (20 mL or 10 mL) or capped HPLC vials. The system can be programmed to collect the sample volumes at predefined time points. The syringe system also offers the facility for auto-replacement and dilution with fresh media. The sample collector enables sample collection for 24 sampling intervals. Automatic sample collector adapts to 5 different types of trays.Sample Collector and Syringe PumpClosed LoopEFD-07 can also be integrated with a media manager to maintain the desired media temperature and provide continuous stirring of media in the media reservoir throughout the test.Closed Loop ConfigurationHeat Exchanger CoilPiston PumpMedia ReservoirAutomated SamplingManual SamplingFlow Through CellSyringe PumpCombination tray (with dilution option)HPLC vialsGlass tubesHPLC and Glass tubes (2 Types)ŸHPLC vials 1.5 mL (8 x 7) + Glass tubes 20 mL (8 x 7)*Customized trays availableSample Collector Tray (ESC-08Dx)* Ÿ1.5 mL (24 x 7)Ÿ20 mL (16 x 7)5ComplianceTouch ScreenX7°CIndividual Cell Temp.

Cell for large medical devices : This cell has a maximum length of 80 mm and is designed to hold longer medical devices.9.Cell for implants: This cell has a small chamber to house the dosage and is used for smaller implants.Flow-Through cells for different dosage forms710. Customized flow-through cells :Using the above cells as the main models, specific holders have also been designed to hold other dosage forms. Customization can be based on the dosage form, media, inner diameters, cell length and holding devices etc. • Holder for creams and gels : An inserted cup facilitates testing on ointments, gels and creams using apermeation membrane. This modification is based on 22.6 mm cell.• Holder for ophthalmic lens : This modification is based on 22.6 mm cell and has an inverted holder thatallows testing on ophthalmic lenses coated with drugs.For intended use of hydroalcoholic media, specially designed PEEK cells are also available•Types of flow :s :There are 2 types of hydrodynamic flow within a flow-through cell viz. a laminar flow and turbulent flow. Laminar flow is achieved by filling the flow-through cell with a 5 mm ruby bead bottom of the cell followed by a layer of 1 mm glass beads as described in the USP . The laminar flow is more controlled as it crosses the dosage form in unidirectional flow. The turbulent type of flow is obtained by placing only the ruby bead in the flow-through cell. The turbulent flow is more beneficial for dosage forms that require a higher agitation rate to release its actives.Experimental ConditionsTurbulent FlowŸSample filtration :Filtration occurs at the top of the flow-through cell with a filter insert of standard filter size of 25 mm. Different types of filters with variety of pore sizes can be used depending on the dosage form. In some cases, multiple filters can be used from larger to smaller pore size. The use of glass wool in the filter section is recommended for dosage forms with highly insoluble or oily particulates .ŸDosage positioning :Solid dosage form: Tablet can be simply placed in the cell on the layer of glass beads or positioned uniformly on atablet clip holder or directly on the ruby bead (turbulent flow). This factor can eliminate problems such as tablet sticking, swelling and floating as seen in other conventional dissolution methods.Suspension :Liquid samples can be placed directly on layer of glass beads or sandwiched uniformly between single or multiple layers of glass beads. This ensures repeatability, reproducibility and reliability of results.Powder :Using the powder granule cell, the powder is simply filled into the cell without any compression or compaction. The filter insert is placed on either side of the cell.Laminar Flowaccepts no liability for any errors and reserves the right to alter specifications without noticeDecember, 2015ELECTROLABSales &Service WorldwideEFD-07M.S. : 1410100110 Volts 230 Volts M.S. : 1420100ModelProduct code Utilize ELECTROLAB ’s dedicated Dissolution Application Lab for confidential MethodDevelopment and Transposition to optimize parameters for NDDS。
