Membrane filter TLPVDF series

hydrophobiclaboratorymedical

Introduction
Hydrophobic PVDF membranes have low surface energy, good heat resistance and broad chemical compatibility. Their hydrophobic nature makes them difficult to wet with aqueous fluids, which suits them to air and gas filtration and applications where liquid intrusion must be avoided.

Key features

• Ultra-low adsorption and low extractables.
• High porosity with uniform pore opening.
• Wide chemical compatibility with many solvents.
• High throughput and flow rate.
• Heat and oxidation resistant; compatible with common sterilisation methods.
• Consistent inter- and intra-lot performance.
• Resistant to autoclave, EO and gamma irradiation (see verification note).
• Can be used for liquid filtration after pre-wetting with 20% ethanol.
• *Sterilisation times/doses vary depending on the customer's process and conditions; verification is required.

Specifications (examples)
TLPVDF022270 — PVDF, Pore size 0.22 μm, hydrophobic, width 270 mm, roll form
TLPVDF045270 — PVDF, Pore size 0.45 μm, hydrophobic, width 270 mm, film form
Note: Other specifications can be customised (minimum order quantity requirements apply).

Applications
Suitable for filtration and separation in food & beverage, pharmaceutical, microelectronics, industrial processes, water treatment and laboratory use.

• Air and gas purification
• Gas emission control
• Solvent filtration and sample preparation
