These supported membranes are hydrophilic and compatible with most solvents and aqueous material. High pore density and narrow pore size distribution make it an extremely precise membrane. No monomers plasticizers adhesives surfactants or wetting agents are used in the manufacturing process which eliminates sample contamination and ensures low protein binding and minimal loss of sample. The Anopore® membrane is supplied in the form of Anodisc™ membrane filters. The membrane is peripherally bonded to an annular polypropylene ring for ease of handling and is suitable for both vacuum and pressure filtration. Virtually transparent when wet making it ideal for microscopy studies. Pore Size: 0.1µm. Diameter: 47mm. 50/Pack. Whatman™ #: 6809-5012.
