Tisch SKU: SF17505

Tisch Scientific PTFE Syringe Filters, 0.45 µm, 4 mm, 200/Pk - SF17505

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PTFE filters aggressive organic solvents without swelling or breakdown while blocking aqueous ingress in vent applications and delivers absolute particle cutoff at the rated pore size. The PP housing stays inert across common laboratory solvents and buffers in routine use while sustaining efficient flow on viscous samples and holds extractables low for sensitive analyses. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Stable across a wide operating temperature range for demanding methods
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Tough polypropylene body tolerates repeated handling at the bench

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis.
