Microbial Limit Tester

The Microbial Limit Tester is a specialized microbial testing device designed and manufactured in accordance with the *Chinese Pharmacopoeia* and relevant industry standards. The device uses negative-pressure filtration to trap microorganisms from the test solution on a filter membrane. After incubation, visible colonies form, and the bacterial count in the sample is accurately determined through counting. It is suitable for microbial limit testing in the pharmaceutical, food, cosmetics, and chemical industries.

Pharmaceutical Industry: Suitable for microbial limit testing of pharmaceutical water (purified water, water for injection), liquid raw materials, and non-sterile pharmaceutical preparations.

Medical Device Industry: Suitable for microbial limit testing of water used in medical device production (purified water, water for injection).

Food and Beverage Industry: Used for microbial testing of bottled water, beer, spirits, fruit juices, and other beverages, as well as liquid raw materials during production.

Public Health Sector: Used for testing total bacterial counts and pathogenic bacteria in water samples such as drinking water and air conditioning condensate.

Chemical Industry: Suitable for microbial testing of various types of water samples.

• Built-in Diaphragm Pump Design: Equipped with a high-performance diaphragm pump that operates quietly and reliably. No external filtration flask is required; filtered samples can be discharged directly, enhancing operational convenience.

• Independent, Removable Filtration Components: The filtration unit features a modular design for easy assembly and disassembly, facilitating cleaning, sterilization, and maintenance.

• Independent Knob Control: The knob-style switch design allows each pump head to be started and stopped independently, providing intuitive operation and improving experimental efficiency.

• Compatible with Rapid In-Line Sterilization: The filter heads can be rapidly sterilized using a flame torch or high-temperature sterilization methods, facilitating continuous operation and helping to control cross-contamination in the laboratory.

• Durable Materials and Easy-to-Clean Design: The housing and filtration components are made of corrosion-resistant materials such as stainless steel. With surface treatments like brushed finishes, the surfaces are smooth and easy to disinfect, helping to maintain a clean laboratory environment.
