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.
- 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
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.
Cytiva business offers a variety of Whatman track-etched membranes. Cyclopore comes in clear and black colors. Nuclepore track-etched membrane options are available for organic halide adsorption, electron microscopy, and other specific applications.
