F47 Microbial Enumeration Funnel can be used in concert with?47mm micro-filtration membrane and the corresponding filter supporter or microbial enumeration tester, to form a microbial enumeration test system. This system can be widely applied to microbial enumeration testing for pharmaceutical, purified water,etc. Based on principles of membrane filtration method, this system separates microbes form the solution,and trapped the microbes on the filter membrane. Stick the membrane on the agar culture-medium.Put it under a specific environment and restore the growth of microbes on the filter.Then count and identify them when they formed some visible colony.
