Polypropylene Syringe Filters, 0.45um, 33mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18219

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 33 mm, 100/Pk - SF18219

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophobic polypropylene suits solvent and non-aqueous sample streams while keeping binding low and capturing particulates through its depth and holds up to aggressive process chemistries. The polypropylene housing contributes minimal extractables to the filtrate while holding a reliable seal against the membrane edge and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples so your downstream method starts with a clean sample.
