LabExact PVDF Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10221

Each hydrophobic vent-rated filter carries manufacturer bacterial retention testing built into the design, letting a vent line stay in continuous service without repeating that testing on site between uses. Hydrophobic PVDF repels water for dependable gas and vent filtration and holds up to alcohols and mild hydrocarbon solvents. Polypropylene construction maintains a low-dead-volume internal flow path while shedding virtually no extractable material into the sample and resists degradation from routine sample matrices. Downstream equipment and work areas stay protected from airborne bacterial contamination once the vent path runs through the membrane.

Membrane Characteristics

• Low extractables preserve a clean chromatographic baseline
• Resistance to hydrolytic degradation exceeds that of nylon membranes
• Hydrophobic surface supports sterile venting of air and process gases
• Fluorinated polymer chemistry resists ozone, UV, and ionizing radiation
• Hydrochloric, dilute nitric, and up to 90% sulfuric acid cause no attack

Housing Characteristics

• Impact-tolerant polypropylene body withstands routine bench handling without damage
• The seal formed against the membrane blocks bypass at rated operating pressure
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Medical-grade polypropylene with broad chemical compatibility

A filter that softens or swells in your solvent fails you mid-run, batch after batch. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run.

• QuEChERS Extract Prep - Removes co-extracted waxes and pigments from QuEChERS extracts, protecting GC-MS and LC-MS systems during pesticide testing.
• Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
• 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.
