Polypropylene Syringe Filters, 3.0um, 25mm, Double Luer Lock, PP Housing, Nonsterile, 100/Pk SKU: SPEC18190

Polypropylene (PP) Syringe Filters - SPEC18190

The 3.0 µm polypropylene membrane configuration delivers specialized performance for applications requiring initial filtration of heavily contaminated samples. With 4.9 cm² of filtration area in a 25mm diameter format, these filters provide efficient coarse particle removal while maintaining hydrophobic properties essential for organic solvent processing. Operating specifications include 72.5 psi maximum pressure with 116 psi burst rating, ensuring safe operation across diverse sample types. The hydrophobic polypropylene construction throughout both membrane and housing delivers consistent chemical resistance for challenging laboratory workflows.

Key Membrane Characteristics

• 3.0 µm polypropylene membrane removes coarse particulates efficiently while allowing high flow rates for rapid sample processing
• 4.9 cm² filtration area handles heavily contaminated samples that would quickly overwhelm finer pore size membranes
• Hydrophobic surface characteristics naturally resist aqueous solutions while permitting organic solvents and non-polar compounds to pass
• Maximum operating pressure of 72.5 psi with 116 psi burst strength accommodates viscous samples and high-particulate matrices
• Temperature tolerance to 80°C enables warm solvent filtration and elevated temperature processing requirements

Key Construction Characteristics

• Polypropylene housing material provides chemical compatibility, matching the membrane for uniform resistance throughout the assembly
• Double luer lock connections on both inlet and outlet secure syringes and receiving vessels during high-pressure operations
• 25mm diameter format balances throughput capacity with manageable size for manual syringe-driven filtration workflows
• Nonsterile configuration allows you to apply autoclave or gamma sterilization when your laboratory protocols require sterile operation

Each filter combines robust construction with broad chemical compatibility, delivering reliable performance for your most demanding prefiltration applications. The polypropylene membrane and housing resist degradation from aggressive solvents, acids, and bases commonly encountered in laboratory operations. Your workflows benefit from the large pore size that maintains high flow rates even with challenging sample matrices, reducing processing time while protecting downstream equipment and finer filtration stages from premature fouling.

• Heavy Particulate Prefiltration - Initial filtration stage for environmental samples containing soil, debris, and suspended solids
• Industrial Effluent Processing - Clarifying wastewater and process streams before subsequent analytical or treatment steps
• Paint Formulation Analysis - Removing large aggregates from coating suspensions while maintaining representative particle distributions
• Food and Beverage Sampling - Processing turbid samples containing pulp, fibers, and sediment before instrumental analysis
• Polymer Solution Clarification - Filtering viscous polymer preparations and resin solutions, where finer pores would create excessive pressure
• Crude Extract Processing - Initial cleanup of botanical extracts and natural product samples before secondary purification steps
