德国罗威邦Lovibond在线浊度仪
PTV 1000低量程
测量原理:
光源组件位于水面之上,不与水体接触,可避免脏污等干扰。
从光源组件发出的光,垂直向下射入浊度仪水体内,遇到水体中的悬浮颗粒后产生散射光。检测器沉浸在水体中,其能够检测到与入射光束呈90度角的散射光。从而检测出水体的浊度值。
同时,浊度仪内置气泡消除系统,该系统能够高效地去除水样中的气泡,有效地消除低浊度测量中最主要的干扰因素。

产品说明:
PBS(phosphate buffered solution)即磷酸盐缓冲液,能够提供相对稳定的离子环境和pH缓冲能力,是生物学中经常使用的缓冲盐溶液,用于分子克隆及细胞培养等,pH为7.2-7.4,与人体血液等渗,主要成分为磷酸二氢钾、磷酸氢二钠、NaCl),KCl),。
PBS是磷酸缓冲盐溶液(phosphate buffer saline)一般作为溶剂,起溶解保护试剂的作用。它是生物化学研究中使用的一种缓冲液,主要成分为Na2HPO4、KH2PO4、NaCl和KCl,由于Na2HPO4和KH2PO4它们有二级解离,缓冲的pH值范围很广;而NaCl和KCl主要作用为增加盐离子浓度。如有需要PBS还可以补加1 mmol/L CaCl2和0.5 mmol/L MgCl2,以提供双价阳离子。
配制方法
含0.05%吐温-20的pH7.4的磷酸盐缓冲液(简称为PBS-T)配制方法为:
称取磷酸二氢钾(KH2PO4),磷酸氢二钠(Na2HPO4·12H2O),NaCl),KCl),吐温-20 ,加水。
PBS:Phosphate Buffered Saline
PBS 1L配方pH7.4:磷酸二氢钾(KH2PO4):0.27g,
磷酸氢二钠(Na2HPO4):1.42g,
NaCl):8g,
KCl):0.2g,
加去离子水约800mL充分搅拌溶解,然后加入浓盐酸调pH至7.4,zui后定容到1L
大部分实验室还是自己配制,不仅麻烦而且耗时,还有些实验室购买现成的PBS溶液,不仅仅保存运输不便而且价格昂贵 其实现在zui方便是使用和购买PBS片剂,不仅价格只有溶液的十分之一,而且运输保存方便,并有多种选择
