SRB Bacteria Test Bottle
Determination of bacteria in water 

Testing principle 

The principle of extinction dilution method was used in the determination of bacteria in water by test bottle method. The water sample to be determined will be injected into the test bottle step by step with sterile syringe for dilution, and each test bottle will dilute the number of bacteria in the water sample by 10 times. Until there is no bacterial growth in the last test bottle, then calculate the bacterial content in the water sample according to the dilution multiple. 

The liquid in srb-hx-14 and srb-hx-7 sulfate reducing bacteria test bottles turns black, with black precipitate or iron nail turns black, indicating the growth of sulfate reducing bacteria. 

Package: 180 pieces / box

SRB细菌测试瓶

水中细菌的测定
测试原理
用绝迹稀释法原理,用试瓶法测定水中细菌。待测水样用无菌注射器逐级注入试瓶稀释,每一试瓶稀释10倍。直到后一个测试瓶中没有细菌生长,然后根据稀释倍数计算水样中的细菌含量。

srb-hx-14和srb-hx-7硫酸盐还原菌试验瓶内液体变黑,有黑色沉淀物或铁钉变黑,说明硫酸盐还原菌生长。
