293 mm Membrane Disc Filters

Durapore Membrane Filters

Durapore (polyvinylidene fluoride) membrane filters are designed to provide strength, flexibility, and broad chemical compatibility for critical biological separations. Protein binding to hydrophilic Durapore membranes is two orders of magnitude lower than nitro-cellulose or PTFE.

MF-Millipore Membrane Filters

MF-Millipore (mixed esters of cellulose) membrane filters are composed of biologically inert mixtures of cellulose acetate and cellulose nitrate.

Low Water Extractable Membrane Filters (TF)

TF filters contain no wetting agent and have a lower water extractable content.

Fluoropore and Mitex Membrane Filters

Fluoropore membrane filters are PTFE bonded to high density polyethylene to improve handling (FS is bonded to polypropylene).

Mitex membrane filters are PTFE without a backing material and are unaffected by many liquids.

Both filter types are biologically and chemically inert, and will meet extreme conditions of chemical compatibility and temperature.
