MilliporeThe membrane filtration method involves using a sterile filter membrane with a certain pore size to trap microorganisms, and then culturing and counting them. This method can be used for microbial limit testing of products, as well as for microbial analysis of rinse water, injection water, and process water. It is recognized as the best testing method in the pharmacopoeias of the United States, Europe, and Japan. Compared with the traditional direct vaccination method, the advantages are obvious:

¨ Not limited by sample volume

¨ Concentrate the analyte and improve sensitivity

¨ Washable inhibitory substances

¨ Can lower the probability of false positives

¨ Effectively utilize the culture medium to save time

¨ Can collect pathogenic bacteria with low pollution levels

MERCK MilliporecompanyMicrofilThe filtration system adopts membrane filtration method, suitable for food/drink/Laboratory microbiological testing of raw materials, semi-finished products, and finished products for beer companies, microbiological limit testing of production water, raw materials, intermediates, and finished products for pharmaceutical companies, and microbiological limit testing for electronic companiesDIMicrobial and limit testing by water microbiological testing and environmental monitoring institutions.

Key Features:

¨ Convenient and easy-to-use system

¨ Easy to use, stackable, lightweight, and recyclable plastic,MicrofilThe funnel avoids the influence of high temperature and high pressure, and also reduces waste

¨ Assembly "MicrofilThe seal between the funnel and the multi link filter membrane bracket is tight and not suitable for clamps orORing to ensure leak free operation and uniform microbial recovery rate

¨ Innovative device design that lifts the filter membrane after filtration, making it easy to remove using tweezers

¨ uniqueMicrofilThe bracket filter is faster than the all glass membrane changing device

¨ Choose a multi filtration bracket for laboratory use

¨ 100mlor250mlFunnel provides convenient funnel distributor

¨ Choose a conventional sterile filter membrane orEZ PackageMembrane purification column

¨ EZ streamThe diaphragm pump directly eliminates waste liquid without the need for waste liquid bottles and safety bottles, which is in line with microbiological analysisISOStandard, efficient filtering speed, silent design, streamlined and compact, no maintenance required
