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
