PTFE membrane filters are available with and without a laminated polypropylene support, PTFE. Inherently hydrophobic, PTFE will not absorb moisture from air or gases, making it ideal for venting applications, phase and aerosol samplings.
Laminated
Laminated PTFE filters are made of a polytetrafluoroethylene polymer laminated to a polypropylene support for improved durability and easy handling. These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols.
Laminated PTFE filters can also be used to filter aqueous solutions when prewetted with methanol. They are autoclavable up to 130°C (260°F). 175µm thick.
Unlaminated
Unlaminated filters are compatible with strong acids, aggressive solvents and high temperatures which can soften the polypropylene support of laminated PTFE. These filters are ideal for applications that require high temperatures and strong acids, without adding particulates to the filtrate. Stable up to 260°C (500°F). 50µm thick (1.0µm is 100µm thick).
Applications
- Aggressive Solvent and Acid Sterilisation, Clarification
