Unit : 2000/pkg (66191 47 mm, grid, gamma-irradiated)

Certified 0.45 μm membrane for microbiological analysis meets or surpasses regulatory requirements

• Mixed cellulose esters is the most accepted filter media for micro-biological analysis, and provides maximum recovery of organisms.
• Unique dot grid pattern provides guidance for quantification of bacterial colonies without growth inhibition or enhancement.
• Suitable for microbiological analysis using the Membrane Filter (MF) Technique.
• Variety of packaging options meets any need. Available in gamma-irradiated, individually packaged S-packs, autoclave packs, or non-sterile packs.
• Use with Pall microbiological ampoule media for high growth levels and easy identification of contaminants.

Applications

• Certified for the microbiological analysis of potable, waste, process,and natural waters in accordance with the MF Technique referenced in Standard Methods for the Examination of Water and Waste- water, current edition, and the U.S. EPA's Microbiological Methods for Monitoring the Environment, 600/8-78-017.
• Ideal for isolation and enumeration of Total and Fecal Coliforms, E. coli, Fecal Streptococcus, fungi, and other heterotrophic organisms.
