Our Fluoropore® membrane is a hydrophobic, polytetrafluoroethylene (PTFE) polymer membrane bonded to a high density polyethylene support to improve the handling characteristics of the filter for normal applications. Fluoropore membranes provide broad chemical compatibility, high flow rates and consistency. (Please note that catalogue numbers containing 'FHUP' are unlaminated, or produced without a backing.) Our Omnipore membrane is a hydrophilic PTFE membrane that is compatible with virually all solvents, acids, and alkaline solutions.

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.
