Polypropylene Syringe Filters, 0.45um, 33mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
Tisch SKU: SF18007

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 33 mm, 100/Pk - SF18007

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Polypropylene resists a broad range of organic solvents, acids, and bases while sustaining throughput as a depth medium and pairs hydrophobic behavior with broad chemical resistance. The PP housing keeps the fluid path low in extractable contamination while routing 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.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through final analysis.
