PTFE Hydrophilic Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Slip, Sterile, 100 /Pk SKU: SF18249

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18249

Pharmaceutical quality control laboratories, clinical diagnostic facilities, and biotechnology research organizations require immediate-use sterile filtration solutions for small-volume samples where contamination control is paramount. Advanced laboratory capabilities demand membrane technology that delivers validated 0.22μm bacterial retention without pre-sterilization delays or additional processing steps. Engineered with compact 13mm architecture and hydrophilic PTFE membrane chemistry, this filtration system provides ready-to-use sterile performance through 43.51psi bubble point integrity validation. Design optimization includes individual sterile packaging eliminating contamination risks, 10μL minimal holdup volume for precious sample conservation, and polypropylene prefilter integration extending membrane life while processing 10ml sample volumes with 5.5ml flow rate efficiency.
