一般描述
ReadyPlate™ CCA plates of 55mm diameter is a selective and differential chromogenic culture medium. It is a standard medium in water testing for simultaneous detection and enumeration of coliform and E. coli by the combination of two chromogenic substrates. The interaction of selected peptones, pyruvate, sorbitol, and phosphate buffer promotes rapid colony growth, even for sub-lethally injured coliform bacteria. The growth of Gram-positive bacteria, as well as certain Gram-negative bacteria, is inhibited by the presence of Tergitol™ 7, with no negative effect on the growth of coliform bacteria. E. coli cleaves both Salmon-GAL and X-glucuronide so that positive colonies take on a dark-blue to violet color. These are easily distinguished from other coliform colonies, which have a pink to red color.
EZ-Pak Filters are ready-to-use, sterile filters made of Mixed cellulose esters (MCE) with 0.45 μm pore size, white, gridded, and 50mm diameter. These filters possess high recoveries.

饮用水检测技术包括定量检测、色谱法、分光光度法、反射法、物理参数测定(如浊点、颜色、硬度、pH、气味)和病原体检测(分子或细胞培养法)。这些质量控制试验既要在工艺过滤(絮凝和澄清等)后的输入水源中进行,也要在过滤后的输出用水中进行(如水龙头取样)。
