Polypropylene Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Nonsterile, 200/Pk
Tisch SKU: SF18019

Tisch Scientific Polypropylene (PP) Syringe Filters, 0.45 µm, 4 mm, 200/Pk - SF18019

Tisch Scientific works with established filtration manufacturers to ensure reliable quality and performance. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The polypropylene matrix delivers nominal retention with high dirt-loading capacity while repelling water in vent and solvent service and tolerates solvents and acids that degrade many membranes. The PP housing prevents sample bypass under rated operating pressure while resisting degradation from routine sample matrices and sustains efficient flow on viscous samples. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.
