LabExact PVDF Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10227

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophobic PVDF repels water for dependable gas and vent filtration while clarifying samples at the rated pore size and tolerates common chromatography solvents without degradation. Polyolefin construction sheds virtually no extractable material into the sample and resists degradation from routine sample matrices. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Limiting oxygen index runs high, supporting flame resistance and low smoke
• Organic solvent resistance beats PES or nylon at comparable pore size
• Hydrophobic surface chemistry gives PVDF a water contact angle above 100 degrees, blocking wetting
• Gamma irradiation sterilization causes no chain scission unlike polypropylene membranes
• Autoclave sterilization cycles leave pore structure and flow performance intact

Housing Characteristics

• Polypropylene housing tolerates ethylene oxide gas sterilization cycles without softening or dimensional distortion
• PP housing supplied sterile in individual packaging for immediate use in aseptic filtration without bench preparation
• Polypropylene housing retains its chemical integrity under vaporized hydrogen peroxide decontamination cycles used in aseptic processing isolators
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion

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 across the organic solvents and harsh reagents your methods use. Standardize your filtration purchases across every method with volume pricing and documentation from the Tisch Scientific team.

• Vial and Tubing Venting - Blocks liquid while venting sealed vials and tubing lines, keeping pressure equalized during fluid transfer steps.
• Compressed Gas Filtration - Passes nitrogen and other inert gases freely while holding back moisture, protecting instruments and gas lines.
• Organic Solvent Filtration - Wets readily with alcohols and mild hydrocarbons, delivering dependable clarification of organic solvent samples.
• Beverage QC - Clarifies wine, beer, and juice samples ahead of HPLC testing for organic acids, sugars, and preservatives.
• Robust Particulate Filtration - Withstands high pressure differentials while handling heavy particulate loads, extending membrane service life.
• Dissolution Testing - Removes undissolved particles from timed USP 711 dissolution aliquots, preventing skewed potency and release results.
