LabExact Tri-Layer PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10410

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PTFE membrane clarifies solvent streams at the rated pore size while blocking aqueous ingress in vent applications and withstands aggressive organics that degrade other media. The PP housing sustains efficient flow on viscous samples while resisting degradation from routine sample matrices and delivers a chemically clean filtrate to the downstream step. Where analytical results depend on clean samples, the preparation step stays consistent from sample to sample through a pre-tested syringe filter.

Membrane Characteristics

• High membrane porosity, 70 to 80 percent void volume, delivers high flow at low pressure
• Absolute pore rating delivers reproducible retention across every protocol
• High porosity minimizes hold-up volume for small sample volumes
• Minimal moisture absorption pairs with a low tare mass
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate

Housing Characteristics

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Resists stress cracking from aqueous salt and buffer solutions

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.
