Microbial Testing Membrane

Microbial detection membrane, unsupported natural hydrophilic mixed cellulose filter membrane and cellulose nitrate membrane, use different pore sizes to enrich designated bacteria for culturing, which is widely used in various microbial analysis and research.

Microorganisms include: bacteria, viruses, fungi and some small protists, microscopic algae and other large groups of organisms. Microorganisms are widely distributed in nature because of their small size, light weight, strong adaptability and strong reproductive ability, and are closely related to humans. They exist in every corner that people can touch, such as medicine, agriculture, food, cosmetics, feed, pharmaceuticals, and the environment.

Microbiological testing, here can be also referred as colony count test, which is  standard for routine microbiological quality control ,plays a vital part for processing test and lot release test in pharmaceutical, food&beverage, cosmetic, municipal water industries to ensure products safety for consumption.

Membrane filtration microbial detection is an internationally recognized microbiological standard test method,approved by organizations such like AOAC, the United States, Europe and Japan, FDA and EPA.

Membrane filtration microbial detection method is easy for operation and has many advantages compared with traditional testing method:

* Compared with direct inoculation,  membrane filtration method can detect large volume of samples at one time.

* Concentration effect improves the testing accuracy.

* Membrane Filters with colonies can be kept as a long-term record of detection.

* Colony is easier for observation and proceed for qualitative and quantitative test.


Biolanbo offers full solution for microbial testing to streamline your microbial testing workflow, including single packed membrane and continuous packed membrane for dispenser, stainless  steel manifold, pre-sterilized disposable funnels, bacterial petri dishes, pumps and freeze-dried powder culture medium.
