Polypropylene Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18220

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 4 mm, 100/Pk - SF18220

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Polypropylene tolerates solvents and acids that degrade many membranes while sustaining throughput as a depth medium and pairs hydrophobic behavior with broad chemical resistance. The PP housing sustains efficient flow on viscous samples and prevents sample bypass under rated operating pressure. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• High resistance to organic solvents, acids, and bases
• Hydrophobic matrix suits solvent and non-aqueous sample streams
• Low binding with nominal depth retention and high dirt-loading capacity
• Sustains throughput on particulate-laden solvent samples
• Low extractables protect sensitive downstream analyses

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Rigid polypropylene body holds its shape under manual filtration pressure
• Stable across the full aqueous pH range in routine sample work
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
