TeflonFlow Filter Cartridges
Hydrophobic PTFE Membrane · Sterilizing Grade

TeflonFlow Filter Cartridges are composed of a hydrophobic PTFE membrane. Characteristics include organic & inorganic corrosion resistance and it's inherently hydrophobic nature. These filters are ideally suited for the sterile filtration of solvents and corrosive and oxidized liquids.



Features and Benefits

  • Inherently hydrophobic
  • Broad chemical compatibility
  • High tolerance for aggressive acids and bases
  • High flow rates
  • Low extractable



Quality Standards:

  • Bacterial quantitative retention of 107 CFU/cm2 Brevundimonas Diminuta (ATCC 19146) according to ASTM F838 methodology .
  • 100% Integrity testing in manufacturing .
  • Each filter is fully traceable with unique serial number.

  • Manufactured in a facility which adheres to ISO 9001: 2015 Practices .

  • Full Regulatory Compliance with following :
    • Bacterial Endotoxin : Aqueous extraction of autocalved filter contains <0.25 EU/ml as determined by Limulus Amebcyte Lysate (LAL),USP<85>.

    • Non-fiber Releasing : Component materials meet the criteria for a "Non-fiber-releasing filter" as defined in 21 CFR 210.3(b)(6).

    • Component Material Toxicity :Meet the requirement of USP <87> In Vitro Cytotoxicity Test ; Meet the Criteria of USP<88> Biological Reactivity Test for Class VI-121℃ plastics

    • TOC/Conductivity at 25 ℃：Autoclaved filter effluent meet the USP<643> for Total Organic Carbon and USP<645> for

    • Water Conductivity per WFI requirements after a UPW flush of specified volume .

    • Particle Shedding : Autoclaved filter effluent meet the USP<788>for large volume Injections .

    • Indirect Food Additive：All component materials meet the FDA Indirect Food Additive requirements cited in 21 CFR 177-182 , and EU framework regulation [1935/2004/EC].
