It is mainly used for the determination of water samples of coliform bacteria by enzyme substrate method. 100ml sterile sampling bottle / quantitative bottle is a product with 51-hole or 97-hole quantitative detection plate , colitech enzyme substrate reagent and program controlled quantitative sealer. According to the instructions, 100ml water samples were accurately measured with 100ml aseptic sampling bottle / quantitative bottle. The reagents were dissolved in the quantitative detection plate / quantitative hole plate, then seal plate with a program-controlled quantitative sealing machine and culture it about 24h, then count the positive cells. Check the MPN table to calculate the MPN concentration value in the water sample.

Packaging specification
