QIS-F301 Microbial Limit Test Instrument
Product Introduction
The QIS-F301 Microbial Limit Test Instrument is designed and manufactured according to relevant pharmacopoeial requirements for microbial limit testing. It is a compact membrane filtration system designed to detect and quantify microorganisms in pharmaceutical products, purified water, water for injection and other liquid samples.
The QIS-F301 uses a high-performance built-in diaphragm pump for direct liquid discharge, eliminating the need for a separate vacuum filtration flask. By combining different pump heads with compatible D60 microbial limit culture devices or D47 filter cups, the instrument forms a complete membrane filtration system.
During testing, the sample solution passes through a sterile membrane filter. Microorganisms in the sample are retained on the membrane, followed by incubation to allow visible colonies to develop. The colonies can then be counted to determine the microbial load of the test sample.

Performance Features
• Built-in high-performance diaphragm pump: Direct liquid discharge without an external vacuum filtration flask.
• Compact design: Small footprint saves valuable laboratory bench space.
• Multiple pump-head compatibility: One main unit can work with two types of pump heads for greater flexibility.
•Three-channel operation: Up to three pump heads can operate simultaneously or be controlled independently.
• Quick pump-head replacement: Pump heads can be rapidly installed and removed for convenient operation.
• 121°C sterilization: Pump heads can be separately sterilized using moist heat at 121°C.
• Rapid flame sterilization: Pump heads can also be quickly flame-sterilized for continuous laboratory testing.
• Simple controls: Illuminated button switches provide intuitive operation.
• Stainless steel housing: Mirror-polished stainless steel surface is smooth, corrosion-resistant and easy to clean and disinfect.
• Efficient filtration: Pump flow rate is ≥2000 mL/min.
• Low operating noise: Noise is ≤60 dB(A) under load.

Working Principle
The QIS-F301 microbial limit test instrument uses the membrane filtration method.
First, the test solution is transferred into the compatible D60 microbial limit culture device or D47 filter cup. The built-in diaphragm pump drives the sample through a sterile microporous membrane.
Microorganisms present in the sample are retained on the membrane while the liquid passes through. After filtration, the membrane is transferred or retained in the appropriate culture system and incubated under specified conditions.
During incubation, viable microorganisms grow into visible colonies. The colonies are then counted to determine the microbial content of the sample, providing a basis for microbial limit testing and quality control.
