Description

• Smooth, gridded polycarbonate track-etched (PCTE) membrane surface efficiently supports microorganism enumeration in a standard plate count
• Extremely low nonspecific absorption 
• Rapid standard plate count results
• Compatible with the direct epifluorescent microscopy filter technique (DEFT), which allows microorganisms to be counted directly on a filter
• DEFT can be conducted in under half an hour, sidestepping the standard > 24 hour process of incubating a microbial sample
• Microscopic membrane filters are made by track-etching (polycarbonate is bombarded with radiation and chemically treated to create sharp, uniform filter pores)
• Designed to trap microbes efficiently; more effective than other filter media for certain microorganisms
