HTY-302 Microbial Enumeration Tester is designed and manufactured in line with the relevant requirements of USP .By matching up dedicated filter or membrane filter with different pump heads, forming a complete membrane filtration device. The test solution should be filtered by membrane filtration in detection. Trap micro-organisms of test solution on the membrane. Rinse to remove antimicrobial resistance of the test solution, and then culture to form visible colonies and count, in order to detect the bacterial content. HTY-302 Microbial Enumeration Tester integrated with vacuum pump system, respectively matching two types of pump heads. It can be used in concert withS60 Microbial Enumeration Monitor or F47 Microbial Enumeration Funnel (?47mm microporous membrane) for microbial limit testing in the areas of pharmaceutical, disease control, food, chemical, cosmetics etc.
