GE’s clear Whatman polycarbonate membrane filters are made from a pure polymeric film that provides exceptional chemical cleanliness during microfiltration, as well as high visibility under the microscope.
- Contaminant free to minimize chemical leaching
- Low tare weight and minimal water adsorption
- Smooth, flat membrane ensures particles remain on the surface for visibility
GE Healthcare’s Life Sciences business offers a variety of Whatman track-etched membranes.Cycloporecomes in clear and black colors.Nucleporetrack-etched membrane options are available for organic halide adsorption, electron microscopy, and other specific applications.
Clear membrane filters for microscopic visibility
Dark particles viewed under a microscope are easier to see when they are on a smooth, clear membrane. The translucent nature of Whatman polycarbonate membrane filters from GE makes them suitable for applications that require viewing of dark particles after microfiltration.
