本系统特别适用在容易受到水质影响的IVF或是DNA、RNA等分子生物学实验。

当然，Milli-Q Synthesis 的产水也可使用在需高灵敏度的HPLC检测上。

其中Milli-Q系列更是所有从事化学分析、生化研究及细胞培养所不可缺少的，该系统以反渗透水、蒸馏水、Elix水或去离子水为进水，随时提供符合美国材料试验学会(ASTM)、美国病理学会(CAP)和临床医学会(NCCLS)规定的I级(试剂级)超纯水。

a)纯化系统将自来水作初步处理，一般包括预过滤（深层过滤及膜过滤）和反渗透或蒸馏法，而反渗透因其污染物去除率达到90%-95%以上，回收率达20%-40%以上，效益比传统纯蒸馏法更理想，因此是Milli-Q超纯水系统的理想进水。

另外，Millipore为配合日渐普及的微量分析，研制出Elix连续电流去离子系统，结合反渗透及连续电流去离子技术的优点——经济高效(R〉5MΩ·cm)，可用于一般实验室作分析用水，又因其出水质量高，如作为Milli-Q的进水，更能提高Milli-Q纯化柱的使用寿命及出水水质。

Milli-Q超纯水器使用指导∙机器要求常态为“PRE-OPERATE”状态,并保持24小时通电,需要经常检查供水水箱是否充足∙取水时,首先将取水开关开至“循环”档，待显示屏显示的电阻率达到18.2MΩ·cm时,才能把取水开关打到“产水档位∙超滤柱的消毒清洗 (针对Milli-QB或Milli-QS型号)定期地清洗超滤柱对于保证水质，延长超滤柱使用寿命是很有必要的。

Milli-Q纯水系统会每两星期定期显示有关信息"START SANIT." 以提醒您应清洗超滤柱。

在系统软件中有两种清洗程序.程序:1 (7小时)这是在大多数情况下运用的主要清洗程序。

使用这程序可以从下午下班前开始并利用晚上休息时间进行清洗。

使用程序1的时候,在启动后21分钟后关闭出水阀，此后系统会自动运行直至第二天早上。

程序2:(8小时)此程序有一个较长的浸泡过程，适用于当超滤柱的流量下降或柱已污染时。

此程序必须从早晨开始。

使用程序2时，必须在程序启动后71分钟关闭出水阀。

此后，系统会自动运行。

开始清洗时必须准备~30升的进水。

清洗操作步骤如下：按操作/待机“OPERATE/STANDBY” 键2 秒钟,使Milli-Q系统处于待机“STANDBY” 状态。

把MILLIPAK 40/20从出水枪上取下将过渡接头拧在出水口上。

将12mm外径的管子接在过渡接头上，管子的另一端通下水道或水槽。

将取水枪扳手扳下，待出水口无水流出(卸压)，再将扳手扳上。

取下清洗口的盖子，把它放在附近，把3克NaOH(A.R.分析纯)(代替消毒氯片ZWCL01F50)放入清洗口。

将清洗口的“S”形盖子旋回原处，确保没有渗漏。

按控制面板清洗“CLEANING”键2 秒钟。

(若要选择程序2，再按一次清洗键)等待10秒钟后选择被确认，显示屏会显示“SAN.CYCLE 1”将取水枪扳手扳下，系统就开始进入清洗程序。

400分钟后将扳手扳回到朝上的位置注:若出水阀未关，系统不会计时清洗时间.清洗结束后，系统自动回到预操作（PRE OPERATE）状态去掉12mm管子和过渡接头，装好MILLIPAK 40/20.Milli-Q超纯水系统又可以正常使用了。

milli-q超纯水仪工作原理一、引言milli-q超纯水仪是一种用于制备高纯度水的设备，广泛应用于实验室、医药、生物技术等领域。

本文将介绍milli-q超纯水仪的工作原理。

二、工作原理milli-q超纯水仪的工作原理主要包括预处理系统、反渗透膜系统、离子交换树脂系统和纯化柱系统。

1. 预处理系统进水经过预处理系统，去除悬浮物、胶体物质、有机物和微生物等杂质。

预处理系统包括粗颗粒过滤器、活性炭过滤器和微孔过滤器。

粗颗粒过滤器能够去除大颗粒的悬浮物，活性炭过滤器则能吸附有机物和余氯，微孔过滤器则能去除微生物和细菌。

2. 反渗透膜系统经过预处理后的水进入反渗透膜系统。

反渗透膜是一种过滤水的膜，具有微孔结构，能够有效去除水中的溶解物质、离子和微生物。

水在反渗透膜上形成一定压力，通过膜的微孔进入膜内，而溶解物质、离子和微生物则被滞留在膜外形成浓缩液。

经过反渗透膜系统的处理，水质得到明显改善。

3. 离子交换树脂系统反渗透膜系统处理后的水进入离子交换树脂系统。

离子交换树脂是一种能够选择性吸附或释放离子的材料。

水中的离子通过树脂床层时，与树脂上的离子发生交换作用，使水中的离子得到进一步去除或净化。

4. 纯化柱系统离子交换树脂系统处理后的水进入纯化柱系统，通过特殊的吸附剂进一步去除残余的有机物和微量离子。

纯化柱系统的吸附剂能够高效地吸附有机物和微量离子，使水质达到超纯水的要求。

三、总结milli-q超纯水仪通过预处理系统去除水中的悬浮物、胶体物质、有机物和微生物，然后通过反渗透膜系统去除溶解物质、离子和微生物，接着经过离子交换树脂系统去除离子，最后通过纯化柱系统去除残余的有机物和微量离子，从而制备出高纯度的水。

这些系统的相互配合使得milli-q超纯水仪能够高效地制备出高质量的水，为实验室和各个行业提供了可靠的实验用水。

实验室超纯水设备设备工艺原理实验室超纯水设备是实验室中常用的设备，用于生产高纯度的水，尤其在高科技领域实验和生产中发挥着不可替代的作用。

本文将介绍实验室超纯水设备的工艺原理。

超纯水的定义超纯水根据不同的标准定义有所不同，但是大多数认为，其在纯度指标上应达到一定精度范围内的极限，如电阻率应该高于18兆欧，总有机碳（TOC）要小于0.1ppb。

超纯水对于高精度实验和生产工艺扮演着至关重要的角色。

超纯水的制备原理实验室超纯水设备的核心原理是蒸馏和离子交换。

原水通常使用纯化水或自来水，首先通过粗滤器过滤去除大颗粒和浮性物质，然后进入蒸馏塔进行蒸馏。

在蒸馏过程中，水被加热蒸发，随后被冷却凝结，这样就可以将一般含杂质的水蒸发掉，以获得更纯净的水。

然而，纯水通过蒸馏之后还是会残留一些杂质和离子，这些残留物质的浓度可能越来越高，会影响水的质量。

因此，需要通过离子交换技术进一步去除这些杂质和离子。

使用离子交换树脂具有去除离子杂质的能力，它能帮助将溶解在水中的离子与树脂上氢、氢氧离子置换，形成无机酸或无机盐，从而达到去除离子杂质的目的。

超纯水设备的主要组成部分实验室超纯水设备包括前处理模块（也称为前处理系统）、反渗透模块、蒸馏模块、离子交换模块和后处理模块。

在这些组成部分中，离子交换模块是确保水质的关键，因为它可以去除水中的离子杂质，大大提高了水的纯度。

前处理模块前处理模块由预处理过滤器、活性炭过滤器、射流氧化过滤器等多个成分组成，主要用于去除水中的大颗粒、胶体、有机物、溶解有机物等。

这个模块的主要目的是为了保护后面的反渗透膜，防止它被过多的杂质堵塞而影响水质。

反渗透模块反渗透模块使用反渗透膜，主要用于去除水中的无机盐和一部分有机物质。

其过程是将水通过高压泵送进反渗透膜中，膜的孔径很小，只有几纳米大小，可以过滤掉溶解在水中的离子、有机物等，而水分子则可以穿过。

蒸馏模块蒸馏模块是用于进一步提纯水质的，通过加热水将其蒸发出来，随后对蒸发出来的水进行冷凝，以取得更为纯净的纯水。

Milli-Q超纯水仪
一、产品特点
MILLIPORE(密里博)超纯水系统中的Milli-Q Biocel系统是为生命科学应用设计的。

对于制备电泳胶、动物细胞培养、DNA重组研究和单克隆抗体的制备等都非常理想，能有效的去除热源和其他细菌副产物。

PyrogardTM5000UF柱能保证非常低的核酸酶和热源水平(<0.001Eu/ml)。

生成的水可用来代替DEPC方法处理过的水。

二、产品资料
MILLIPORE(密里博)超纯水系统 Milli-Q Biocel 除热源(Pyrogen)以及动物细胞培养专用。

MILLIPORE(密里博)超纯水系统中的Milli-Q Biocel以5000分子量的UF膜，将水中热源的浓度减低至0.02EU/ml以下。

因此最适用于易受微量蛋白质或是糖类等影响，而阻碍发育的动物细胞培养。

Milli-Q Biocel具有每3小时自动润洗UF膜的功能，所以可使UF膜维持在最佳状态。

此外还可利用面板按纽控制，加入药液后，该系统即以程式化流程自动将UF膜清洗消毒，因此可不断的提供品质稳定的超纯水。
