SANIpore® TFEG Capsule Filter

Single-layer PTFE membrane for fine particle removal

SANIpore® TFEG products are tailored to meet the specific needs of the electronics and high-purity chemical industries, and SANIpore® TFEG cartridge and capsule filters are

manufactured with monolayer polytetrafluoroethylene (PTFE) membranes. This membrane has excellent resistance to almost all chemicals. Therefore, for the chemical industry, SANIpore® TFEG filters are the first choice.

Excellent chemical compatibility in SANIpore® TFEG filters. In the filtration of gaseous and non-aqueous liquids, it can be very effective in removing particles, saving customers time and effort.

SANIpore® TFEG filters are often used as final filters at points of use, especially on tools. In addition, customers can order pre-wetted water for applications in aqueous solutions, providing additional convenience and efficiency, better-reducing replacement costs and extending service life.

Pore sizes ranging from 0.05 to 5.0 µm, these filters offer versatility for various filtration needs. SANIpore® TFEG filters are a reliable choice for critical filtration applications.

General application full-size capsule filters are 100% integrity tested in the process of manufacture. The filter element inside the capsule is constructed of a single-layer expanded polytetrafluoroethylene membrane. It offers broad chemical compatibility, a higher filter area with high flow rates at low-pressure drops, and low extractability.

Common questions about Sanitek

Common Questions about SanitekWhat is GasFlow EPTF Capsule filter material?

GasFlow EPTF capsule filters are 100% integrity tested in the process of manufacture. The filter element inside the capsule is constructed of single-layer expanded polytetrofluoroethylene membrane. It offers broad chemical compatibility, higher filter area with high flowrates at lowpressure drops, and low extractables.

Common Questions about SanitekWhat are GasFlow EPTF filters used for?

GasFlow EPTF products are tailored to meet the specific needs of the electronics and high-purity chemical industries, and GasFlow EPTF capsule filters are manufactured with monolayer polytetrafluoroethylene (PTFE) membranes. This membrane has excellent resistance to almost all chemicals. Therefore, for the chemical industry, GasFlow EPTF filters are the first choice.

Excellent chemical compatibility in GasFlow EPTF filters. In the filtration of gaseous and non-aqueous liquids, it can be very effective in removing particles, saving customers time and effort.

Common Questions about SanitekWhat is the difference between PES and PVDF filter membranes?

The main difference lies in their chemical compatibility and filtration properties. PES (polyethersulfone) membranes offer excellent compatibility with a broad range of solvents, acids, and bases. They are known for their low protein binding and high flow rates.

PVDF (polyvinylidene fluoride) membranes, on the other hand, have superior chemical resistance, making them suitable for aggressive solvents and strong acids. PVDF membranes also provide high protein binding capacity, making them ideal for protein-based applications. The choice between PES and PVDF depends on the specific requirements of the filtration process, including chemical compatibility and protein retention needs.

Common Questions about SanitekHow do you guarantee the quality of your filters?

All materials meet the specifications for biological safety per USP Class V1-121 C for plastics. Materials of construction comply with FDA regulations for food and beverage contact use as detailed in the US Code of Federal Regulations, 21CFR. Materials used to produce filter media and hardware are safe for use in contact with foodstuffs in accordance with EU Directives 10/2011.
