Microbial limit filtration bracket STV3

Microbial limit filtration bracket specifications include: NAI-STV3, NAI-STV6

Product Description

The microbial limit filtration bracket and filter cup form a microbial filtration system. When in use, place the filter membrane on the pump head and fix it tightly with a filter cup to form a complete filtration device. Based on the principle of membrane filtration, separate the sample solution from microorganisms and trap them on the filter membrane. Transfer the filter membrane and cultivate it under specific conditions to restore the growth of microorganisms on the filter membrane, forming visible colonies. Then, perform colony counting and identification.

Application Range

Suitable for laboratory microbiological testing of raw materials, semi-finished products, and finished products in food/beverage/beer enterprises, microbiological limit testing of production water, raw materials, intermediates, and finished products in pharmaceutical enterprises, microbiological testing of deionized water in electronic enterprises, and microbiological and limit testing in environmental monitoring institutions.
