The MCE gridded membrane filter is made of a mixture of nitrocellulose and cellulose acetate and are one of the most widely used filters in analytical and research applications. The surface of the Gridded MCE filter membrane is smooth and flat, which is convenient for microscopic observation. 3.1 mm intervals grid facilitates counting colonies on the filter surface without compromising colony growth. Meet the quality inspection needs of pharmaceutical and other industries.

Features

  • Gridded for better identification
  • Excellent microbial retention efficiency

Can Cobetter gridded membrane filters be autoclaved?

No. MCE grid membrane filters are primarily composed of nitrocellulose and cellulose acetate. At temperatures around 60–80°C, the membrane undergoes glass transition, and thermal decomposition may occur above 120°C. It is recommended to consider gamma irradiation sterilization instead.

What are the sterilization efficiency and microorganism recovery rate specifications for Cobetter gridded membrane filters?

Cobetter gridded membrane filters demonstrate a sterilization efficiency of LRV > 7 and a microorganism recovery rate of ≥ 80%.

What's the grid interval of the gridded membrane filters?

Grid interval: 3.1 x 3.1mm.

What's the maximum temperature tolerance of gridded membrane filters?

The maximum temperature tolerance is 130 °C.

What are the features and advantages of Cobetter MCE gridded membrane filters?
  • Uniform microporous structure that supports consistent, high flow rates.
  • High microorganism recovery and high particulate (dirt) loading capacity.
  • Free of surfactants, minimizing the risk of sample interference or contamination.
  • Clearly and uniformly printed grid, enabling reliable particle observation and accurate enumeration of microorganisms and colonies; the grid material is non-toxic and non-inhibitory to microbial growth, ensuring sample integrity and compliance with microbiological testing requirements.
