Product specification

Ultra-pure; chemically inert

Use for filtration of corrosive liquids or gases up to +204 °C, depending on application

Compatible with virtually all solutions

Non-clogging

Fine and extra-fine grades may shrink at temperatures above +66 °C.

Zitex^® membranes act as "depth filters" with high retention efficiency and non-clogging characteristics. They are used for filtration of corrosive and other aggressive chemicals or gases up to +204 °C. Unlike cellulose filter paper, the PTFE interstices are bonded together resulting in a stabilized pore configuration. This unique combination of depth filter and screen characteristics creates a highly effective filter media. Zitex^® membranes have a better controlled pore size distribution than other high temperature, chemically resistant membranes with similar pore size ratings.

Zitex^® filters are strong enough to be self supporting and may be used without any additional backing material, which could compromise results. The non-stick nature of Zitex^® provides excellent filter cake release properties.

Zitex^® may be sterilized with steam or bactericidal solutions. It is suitable for chromatography solvent filtration and degassing. Zitex^® membranes are inherently hydrophobic, which makes them ideal as venting devices. However, aqueous solutions may be filtered by using pressures exceeding the membrane’s water initiation pressure, or with the aid of wetting agents, such as methanol or ethanol. Disks are interleaved with separators for cleanliness and ease of handling.
