AseptiSure TH 5", 10", 20", 30"

mdi AseptiSure TH PTFE cartridge filters are specially designed high temperature resistant PTFE filters which are steam sterilizable at upto 135°C. These filters are validated with liquid microbial challenge test as per ASTM F 838-05 to offer absolute retention even under high moisture conditions.

These are also validated for other key performance parameters such as chemical compatibility, extractable, heat stability, flow rates, blow through and ability to withstand accidental reverse pressure. These are available in a variety of pore sizes to suit specific microfiltration needs in critical and specialized process applications for air as well as liquid.

  • Absolute retention
  • Essentially hydrophobic
  • High heat stability
  • Wide chemical compatibility
  • Heat sealed
  • No leaching
  • 100% Integrity tested
Consistent and Reliable Quality:AseptiSure cartridge filters are produced with ISO 9001-2008 certified quality management systems.
Regulatory Compliance:
Meet all pharmacopeial and compendia requirements and are registered with USFDA DMF #015554
Low Protein Binding:
Results in increased overall product yield and higher throughputs with biological streams
High Throughputs:
Translates to lower filtration costs, less number of filter changes and overall economy of operations.
Total Traceability
Unique identification number is laser etched on each other.
