Product catalog summary

Product Description
SMT pleated PTFE membrane filters are designed for bioburden control and sterilization of oxidizing, corrosive, and aggressive liquids in the Food & Beverage, Pharmaceutical, and Chemical industries. They feature a single-layer asymmetric, hydrophobic PTFE membrane validated for bacterial retention, integrated into a robust housing suitable for various operational conditions.

Devices
Available in scalable cartridges, mini cartridges, and capsules, SMT filters facilitate easy production scale-up without the need for requalification, as they use consistent media and materials across all sizes.

Compatibility
Constructed entirely from polypropylene using thermal welding, SMT filters offer broad chemical compatibility and can be chemically regenerated, ensuring a small extractable footprint.

Documentation
Manufactured under an ISO 9001 certified Quality Management System, SMT filters comply with EU and US regulations for materials in contact with foodstuffs, ensuring suitability for food and beverage applications.

Key Features

Hydrophobic PTFE membrane, integrity testable
High flow and low pressure drop
Wide chemical compatibility
Validated bacteria retention (0.2µm)

Applications
SMT filters are used in the Pharmaceutical, Cosmetics, and Chemical industries for sterilization of aggressive liquids, absolute retention of particles, and filtration of oxidizing liquids.
