LabExact PVDF Syringe Filters, 0.22 µm, 30 mm, 100/Pk - LE-IWT-ES10332
A single-use hydrophobic vent filter reaches sterilizing-grade retention on a vent line without the autoclave cycle or in-line housing a reusable gas filtration setup would require. Hydrophobic PVDF passes gases freely while holding back water while achieving sterile-grade retention at sub-micron pore sizes and resists HPLC mobile phases, alcohols, and mild hydrocarbons. The polypropylene housing holds its seal true run after run while shedding virtually no extractable material into the sample and resists degradation from routine sample matrices. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.
Membrane Characteristics
- Limiting oxygen index runs high, supporting flame resistance and low smoke
- Fluoropolymer chemistry resists microbial and fungal degradation
- Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack
- Resistance to hydrolytic degradation exceeds that of nylon membranes
- Bacterial challenge testing with Brevundimonas diminuta at 10 million CFU per cm2 confirms sterilizing grade
Housing Characteristics
- Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
- Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
- The seal formed against the membrane blocks bypass at rated operating pressure
- Plasticizer-free polyolefin construction keeps the fluid path clean
An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.

- Bioreactor Vent Protection - Repels water while venting bioreactors and fermenters, keeping process air and gases moving freely through the line.
- Beverage QC - Clarifies wine, beer, and juice samples ahead of HPLC testing for organic acids, sugars, and preservatives.
- Dissolution Testing - Removes undissolved particles from timed USP 711 dissolution aliquots, preventing skewed potency and release results.
- Sterile Tank Venting - Blocks aqueous ingress on storage tanks and carboys, letting sterile air and gas pass through the vent line.
- Culture Vessel Filling - Equalizes pressure in sealed culture vessels by venting displaced air, keeping fill and drain lines fully closed.
- Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
