Polytetrafluoroethylene (PTFE) Syringe Filters
Manufacturer: CELLTREAT
The CELLTREAT PTFE (Polytetrafluoroethylene) Syringe Filters are engineered for the most demanding laboratory filtration tasks. PTFE is inherently hydrophobic and offers nearly universal chemical resistance, making these filters the gold standard for clarifying strong acids, aggressive organic solvents, and alkali solutions that would destroy other membrane types. These filters feature a robust design where the membrane is heat-sealed directly into the polypropylene housing. This adhesive-free construction eliminates the risk of "leachables" or "extractables" contaminating your samples, ensuring high-purity results for HPLC and analytical chromatography.

Lead Times May Vary.
Choose between sterile, individually wrapped packs for sensitive cultures or bulk non-sterile cases for routine laboratory analysis.
Features:
- Adhesive-Free Integrity: The ultrasonic/heat-molded seal provides a reliable barrier without glues, ensuring the housing can withstand high pressures without leaking.
- Hydrophobic Nature: Ideal for gas filtration, venting applications, or the filtration of non-polar organic solvents.
- HPLC Certified Performance: Low hold-up volume and minimal extractables ensure that your baseline remains clean during sensitive chromatography runs.
- Easy Identification: Units are color-coded and the membrane type is clearly inscribed on the housing to prevent laboratory errors.
Application Insights:
- Aqueous Filtration Note: Because PTFE is naturally hydrophobic, it will resist the flow of water-based (aqueous) samples. For aqueous filtration, the membrane must be "pre-wetted" with a small amount of alcohol (e.g., Ethanol or IPA) before the water-based sample can pass through.
- Pore Size Selection: Choose 0.22 µm for fine particle removal and sterile applications; use 0.45 µm for general clarification and degassing of chromatography solvents.
- Pressure Safety: The Female Luer-lock inlet ensures a secure, threaded connection to the syringe, preventing "pop-offs" when filtering viscous or difficult solutions.
