Supplier: Merck

PVC membrane filters are specified by ASTM, NIOSH, and OSHA in air monitoring applications to analyse silica, carbon black, metals, quartz particulates and others.

Supplier: Sartorius

PES membrane filters are hydrophilic, have high flow rates thanks to the symmetric structure, have a low non-specific protein adsorption and are chemically resistant over a pH range of 1 to 14. They are recommended for the filtration of aqueous solutions as well for the protein filtration. Furthermore, the low level of extractables makes them suitable for environmental analysis.
