Microbial Limit Testing ApparatusBYW-300
Detailed Introduction
Product Overview:
The BYW-300 Microbial Limit Testing Apparatus is constructed from stainless steel metal material and equipped with a built-in imported diaphragm liquid pump. It eliminates the need for an external suction flask, as liquids are directly discharged through the diaphragm pump, reducing the complexity associated with suction flask usage and avoiding issues such as slow filtration speed due to poor connections.
Working Principle:
Inject the sample into the microbial limit culture apparatus. Using the built-in imported diaphragm liquid pump for negative pressure filtration, microorganisms in the sample are retained on the filter membrane. The membrane is then removed with a membrane extractor, transferred to a prepared solid culture medium with the bacterial side facing up, and laid flat. The lid is closed to form a sealed culture box, which is placed in an appropriate constant temperature incubator for cultivation and counting.
Application Scope:
Pharmaceuticals: Purified water, water for injection, ophthalmic preparations, active pharmaceutical ingredients, capsules, biological products, tablets, oral preparations;
Food: Purified water, mineral water, beverages;
Chemical Industry: Various water samples requiring microbial testing;
Cosmetics: Various water and product samples;
Disease Control: River, lake, sea, and other water samples.
Product Features:
1. The filter cup features a unique lip seal design, eliminating the need for clamps and O-rings, ensuring leak-free operation and uniform microbial recovery rates;
2. Pre-sterilized filter membranes, ready to use upon opening, minimizing primary contamination sources and enhancing detection reliability;
3. Direct suction filtration and liquid discharge, no suction flask required, easy installation and use;
