Cobetter MCE gridded membrane filters are made of a mixture of nitrocellulose and cellulose acetate, which are one of the most widely used filters in analytical and research applications. They are available in 47mm diameter with 0.45μm or 0.22μm, white or black membrane with grid. The MCE gridded MCE membrane filters with smooth and flat surface feature easy counting of colonies and high bacterial recovery rate.

Features

  • High flow rate and flux
  • Sterile individually packed and ready to use
  • Grids for easy counting without restraining colony growth
  • Excellent bacterial recovery rate
  • Dispenser-ready membrane filter is compatible with other lab dispensers

Applications

  • Microbial enumeration
  • Bioburden testing of pharmaceutical and cosmetic products
  • Bacterial analysis of water and beverages

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.
