LabExact PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10201

Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. PTFE delivers absolute particle cutoff at the rated pore size while filtering aggressive organic solvents without breakdown and resists attack from the harshest process chemistries. The polypropylene housing routes flow to minimize backpressure in service and stays inert across common laboratory solvents. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Strong oxidizing agents like nascent chlorine and concentrated sodium hydroxide cause no attack
• UL 94 V-0 rating confirms the highest self-extinguishing classification
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Minimal moisture absorption pairs with a low tare mass
• High porosity minimizes hold-up volume for small sample volumes

Housing Characteristics

• Stable across the full aqueous pH range in routine sample work
• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating pressure
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

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 from initial prep through final use.
