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. The PVDF membrane delivers bacterial retention at the rated pore size while passing gases freely and holding back water and tolerates common chromatography solvents without degradation. Polypropylene construction maintains a low-dead-volume internal flow path and delivers a chemically clean filtrate to the downstream step. No separate sterilization cycle is needed when the gas path already runs through a validated sterile-grade membrane.

Membrane Characteristics

• Autoclave sterilization cycles leave pore structure and flow performance intact
• Vapor-phase hydrogen peroxide decontamination cycles leave the membrane intact
• Resistance to hydrolytic degradation exceeds that of nylon membranes
• Chemical compatibility spans the full pH 1 to 14 range
• Hydrophobic surface chemistry gives PVDF a water contact angle above 100 degrees, blocking wetting

Housing Characteristics

• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Medical-grade polypropylene with broad chemical compatibility
• Standardized luer connection geometry provides secure engagement with standard syringe tips

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Reliable solvent prefiltration keeps a stray particulate from carrying into your downstream work before it carries into further processing.

• Dissolution Testing - Removes undissolved particles from timed USP 711 dissolution aliquots, preventing skewed potency and release results.
• Vial and Tubing Venting - Blocks liquid while venting sealed vials and tubing lines, keeping pressure equalized during fluid transfer steps.
• QuEChERS Extract Prep - Removes co-extracted waxes and pigments from QuEChERS extracts, protecting GC-MS and LC-MS systems during pesticide testing.
• Bioreactor Vent Protection - Repels water while venting bioreactors and fermenters, keeping process air and gases moving freely through the line.
• Organic Solvent Filtration - Wets readily with alcohols and mild hydrocarbons, delivering dependable clarification of organic solvent samples.
• Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
