For bioburden reduction of process gases, non-aqueous liquids and tank vent filtration.
BTM filters are constructed with a Polytetrafluoroethylene (PTFE) membrane and are used for bioburden control in non-aqueous liquids, process gases and tank vent filtration. Pore sizes range from 0.10 to 5.0 µm and filter sizes scale from laboratory to full production using identical materials to ensure consistent results.
These single-layer, hydrophobic filters are optimized for flow and throughput and resist wetting by airborne water droplets, making them ideal for air and gas applications. BTM bioburden control filters protect processes and extend the life of sterilizing filters. Each cartridge module is individually tested using the water intrusion method before it is released from manufacture.
Applications
- Compressed Air
- Pressurized Gases
- Fermentation Air

Validation
BTM filters are validated using test procedures that comply with ASTM F 838-15(ae1) protocols for the determination of bacterial reduction in filters used for liquid filtration. The filters are challenged with the organisms listed below.
- 0.10µm: Brevundimonas diminuta
- 0.22µm: Brevundimonas diminuta
- 0.45µm: Serratia marcescens
Quality Assurance
BTM filters are 100% integrity tested. CPF filters are developed and manufactured under an ISO 9001:2015 certified Quality Management System and designed to be used in cGMP-compliant processes.
BTM Cartridges
Available from 5-40 inches in length with several end connections and O-ring options.
BTM Capsules
These filters are BTM cartridges encapsulated in a polypropylene shell to minimize exposure to process fluids. A popular choice for single-use applications and can be disposed of easily. Sizes range from 2-30 inches in length.
