LabExact PTFE Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10027
Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. PTFE holds consistent absolute retention at the rated pore size and blocks aqueous ingress in vent applications. The polypropylene housing preserves sample chemistry across the flow path while holding its seal true run after run and is supplied pre-sterilized in individual packaging for sterile sample preparation. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.
Membrane Characteristics
- Stable across a wide operating temperature range for demanding methods
- Biological inertness resists enzymatic attack from proteases and lipases
- Non-fibrous, fully synthetic structure sheds no fibers into filtrate
- Strong oxidizing agents like nascent chlorine and concentrated sodium hydroxide cause no attack
- UL 94 V-0 rating confirms the highest self-extinguishing classification
Housing Characteristics
- Polypropylene housing retains its chemical integrity under vaporized hydrogen peroxide decontamination cycles used in aseptic processing isolators
- Optimized internal geometry minimizes backpressure in service
- Stable across the full aqueous pH range in routine sample work
- Standardized luer connection geometry provides secure engagement with standard syringe tips
An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on from initial prep through final use.
