Microbial limit detector HTY-310

for the pharmaceutical industrybenchtop

Introduction
The HTY-310 Microbial Limit Tester is designed to meet pharmacopeial membrane-filtration requirements. It integrates up to four pump heads, SIP automatic sterilization and a built-in diaphragm pump with direct waste discharge. Samples are filtered through membranes to retain microorganisms, which are then incubated to form colonies for enumeration and microbial quality assessment.

Features

• Color LCD with tempered glass touch panel for intuitive control.
• Built-in SIP automatic disinfection program compatible with 121°C moist heat.
• Countdown runtime and configurable pump head runtime per channel.
• Selectable pump heads (PF47, PB47, PF60, PS60) compatible with S60/F47/F60/F47B consumables; pump heads withstand autoclaving.
• Rapid flame sterilization option for continuous operation.
• Integrated diaphragm pump with direct drainage, eliminating the need for filter bottles.
• Built-in check valve to prevent backflow and cross-contamination.

Applications
Used to assess whether non-sterile pharmaceutical products comply with established microbial limits by membrane filtration and colony count.

Pharmaceuticals: testing purified water, water for injection and finished products.

Food & Beverage: total colony count in beverages, mineral and purified water.

Environmental & public health: total bacterial counts and pathogen screening in water samples (e.g., HVAC condensate, drinking water).
