Contrasting Membrane for
Microbiological Analysis
- Dark background provides excellent contrast for counting opaque colonies in microbiology labs
- Exclusive dot grid pattern does not enhance or inhibit colony growth
- Certified for use in the Membrane Filter (MF) Technique as described in Standard Methods for the Examination of Water and Wastewater, current edition
- Sharp contrast between black membrane and white grid line provides guidance while viewing and counting
- Available non-sterile or in individual gamma-irradiated packs (S-packs) for critical applications
- Excellent membrane for the isolation and enumeration of yeast and mold colonies
- Spoilage organism monitoring and identification in food and beverage quality control laboratories
