Zefon FPC4525 FILTER, 25mm, 0.4um, POLYCARBONATE, PLAIN WHITE
Polycarbonate track-etch (PCTE) membrane filters are precision, two dimensional, microporous screens. As in the case of other screens, particle capture takes place on the surface.
Features:
- Smooth glass-like surface with cylindrical pores for maximum particulate capture
- Suitable for air monitoring
- Lowest, non-specific binding membrane
- Precise pore sizes and pore distribution for absolute filtration and separation
- Non-staining, providing an exceptional background for sample observations.
- Very low extractables
- PCTE membranes pass all USP Class VI tests
- Biologically inert.
- Optically transparent in most pore sizes.
- Excellent chemical resistance and thermal stability.
- Capture of samples on a flat, smooth, glass-like surface, with even distribution in one plane.
- Exceptionally low tare weights, non-hygroscopic, and low trace element level.
- Superior strength
