LabExact MultiDensity Glass Fiber (GF) Syringe Filters, 1.2 µm, 25 mm, 100/Pk - LE-IWT-ES-10704

Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. Glass fiber captures particulates throughout its depth for high loading capacity and accepts water-based samples on contact. Polypropylene construction maintains a low-dead-volume internal flow path while keeping sample purity intact through the filtration pass and presses snugly against the membrane during the pass. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Low-ash borosilicate fiber keeps inorganic contamination minimal in analytical filtrates
• Handles acidic, neutral, and mildly alkaline aqueous samples without matrix degradation
• Compatible with common biological buffers including phosphate, Tris, HEPES, and borate
• Extends filterable sample volume three to seven times versus unprotected media
• Inorganic matrix withstands repeated aqueous exposures without swelling or structural change

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
• Stable across the full aqueous pH range in routine sample work

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.
