Overview
Polydisc TF and ReZist
Home | Filtration Devices | In-line Filters | Polydisc TF and ReZist

This device features a PTFE membrane which is ideal for chemically aggressive solutions, reagents and organic solvents. This lightweight unit is particularly suitable for protective vents and for in-line filtration and isolation applications. The 1 µm device features a polypropylene prefilter for use with heavily contaminated samples.

Features and benefits
  • Solvent resistant membrane
  • Chemical resistant housing
  • Hydrophobic PTFE membrane
  • Autoclavable (multiple times)
  • Integrity-testable (bubble point or water breakthrough pressure ‘in situ’ methods) 
  • Biosafe
  • Lightweight (11.5 g for Polydisc and 17.9 g for ReZist); avoids the collapsing of tubing which can be caused by heavy filter devices

Applications
  • Pharmaceutical: vents and in-line applications
  • Biotech: sterile vents and exhausts for growth environments, in-line sterilization of gases
  • Laboratory: clean or sterile gases. Filtration of solvents and reagents. Drying gases.
  • Electronics: photoresists, solvents, gases for research
