Whatman™ Polyethersulfone Membrane Filter, 47 mm

Whatman™ polyethersulfone (PES) membrane filters from GE Healthcare's Life Sciences business are hydrophilic and stable in alkaline pH, making them suitable for biological samples and aqueous applications. Tissue culture applications often require a sterile membrane that exhibits low protein binding, which allows for an approximation of in-vivo conditions under which the cells would normally be found. Low protein binding PES membranes with low levels of extractable are appropriate for tissue culture applications after they are sterilized. GE's PES membrane filters provide a smooth membrane to retain and enumerate microorganisms on the filter surface. The white surface allows easy counting of dark bacteria and artifacts in a variety of microbiology studies.

• Low protein binding minimizes non-specific protein adsorption
• Hydrophilic membrane suitable for aqueous applications, especially in alkaline pH
• Smooth surface for easy enumeration of microorganisms
• For aqueous applications and for biological samples
