Cytiva's Whatman Cyclopore polycarbonate membranes are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration characteristics of track-etched membranes. Whatman Cyclopore track-etched membrane filter circles are suitable for a wide variety of applications, from general filtration, including cross-flow filtration (tangential flow filtration), to air and water monitoring, microorganism analysis, and many healthcare applications, including immunodiagnostics.

• Low affinity for stains improves visibility under a microscope
• Low nonspecific protein binding minimizes sample loss of proteinaceous samples
• Narrow micropore size distribution and high pore density support rapid surface capture of analyte
• Negligible absorption and adsorption of filtrate; nonhygroscopic
• No particle shedding enables clean filtrate
• Biologically inert
