Smart Microbial Limit Tester

The Intelligent 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.

• Adjustable filtration time: Supports customization of filtration time parameters, effectively preventing insufficient filtration of test solutions due to operator error and improving test consistency.

• Integrated multi-diaphragm pump design: Features multiple built-in high-performance micro-diaphragm pumps that operate quietly. No filtration bottles are required, and filtered liquid is discharged directly, making operation more convenient.

• Flexible Sterilization Methods: The filtration units support rapid flame sterilization and in-line disinfection; when using disposable filter cups, the pump head features a plug-and-play design for easy assembly and disassembly, and compatibility with various sterilization methods.

• Backflow Prevention: Utilizes new backflow prevention technology to effectively prevent liquid backflow, minimizing the impact of operational errors on test results.

• Multi-channel independent control: Multiple filtration units can be started or stopped simultaneously or individually, meeting parallel testing requirements and improving work efficiency.

• Easy-to-clean design: The entire unit’s housing is made of stainless steel, treated with processes such as brushing, resulting in a smooth and flat surface that facilitates daily cleaning and disinfection.
