Whatman Polydisc TF In-Line Filters from Cytiva are lightweight devices with high chemical and solvent resistance that are particulraly suitable for protective vents or in-line filtration applications.

• Chemically resistant hydrophobic PTFE membrane is well suited as a solvent filter for many different solutions
• Filter can be autoclaved multiple times without losing integrity
• Integrity-testable (bubble point or water breakthrough pressure in situ methods)
• Lightweight to prevent tube collapsing

Filtering organic solvents and aggressive solutions calls for a chemically resistant, durable membrane. Cytiva's Polydisc TF features a PTFE membrane resistant to such compounds. The 1 µm membrane features a polypropylene prefilter for solvent filtration containing high particulate density in order to extend the useful life of the membrane.
