The HTY-102S Microbial Limit Tester is a specialized device designed according to pharmacopeia requirements. It features single pump heads, SIP sterilization, high-performance diaphragm pump, and direct waste discharge. By using different pump heads with funnels or canisters, it forms a complete membrane-filtration setup. During testing, the sample is filtered to retain microorganisms on the membrane, which are then cultured into visible colonies for counting to determine microbial levels.
