SWT PTFE Absolute Filter Cartridges

Absolute Cartridges

0.2 Micron PTFE Filter Cartridges

SWT's PTFE Pharmaceutical Liquid Bacterial Retentive (LBR) cartridge is validated to produce sterility through retention of Brevundimonas diminuta per HIMA guidelines. PTFE exhibits high air and liquid flow rates as well as being a sterilizing grade filter that uses an expanded PTFE membrane. Users expecting the ultimate flow rate performance for liquid or air sterilization will find the SWT PTFE filter cartridge to be their preferred choice.

SWT PTFE filter cartridges are manufactured utilizing a certified Class 10,000 cleanroom that operates under the guidelines of the FDA's Good Manufacturing Practices for Medical Devices. All modules are flushed with high purity, non-pyrogenic deionized water, 100% integrity tested, and serialized to provide complete product traceability. A Certificate of Quality accompanies each completed cartridge detailing all lot, audit, and general testing requirements.
