Microbial limit detector HTY-302

for the pharmaceutical industrybenchtopvacuum

Product overview
The HTY-302 Microbial Limit Tester is a membrane-filtration system designed to meet pharmacopeia requirements for microbial limit testing. Equipped with three independent pump heads and a built-in high-performance vacuum pump used with a waste liquid bottle, the unit accepts multiple pump-head types to form a complete filtration workflow. Samples are filtered to retain microorganisms on the membrane; retained organisms are then incubated and counted as colonies to determine microbial levels.

Key features

• Four types of pump heads available for selection and pairing with different filter cups.
• Pump heads compatible with moist heat sterilization (selectable up to 121°C).
• Quick flame sterilization supported for rapid turnaround during continuous operations.
• Each pump head operates independently for parallel processing.
• Built-in vacuum pump used with a filter/waste bottle for secure drainage.
• Check valve fitted to prevent backflow and reduce contamination risk.

Applications
Used to determine whether non-sterile pharmaceutical products meet established microbial quality specifications. The HTY-302 supports membrane filtration workflows commonly required in QC and microbiology laboratories.

Typical application areas

• Pharmaceuticals: microbial limit testing of purified water, water for injection, and drug preparations.
• Food & Beverage: total colony counts in beverages, mineral water and purified water.
• Public health & environmental testing: total bacterial counts and pathogen screening in water samples such as condensate and drinking water.
