Polypropylene (PP) Syringe Filters - SPEC18189
Modern laboratories require prefiltration solutions that handle high-particulate samples without compromising downstream analysis or clogging finer membrane stages. Polypropylene membrane technology at 1.0 µm pore size delivers efficient coarse particle removal while maintaining exceptional chemical compatibility with aggressive organic solvents. Your prefiltration workflows benefit from the hydrophobic membrane's resistance to acids, bases, alcohols, and challenging solvent systems that would degrade cellulosic or polyamide alternatives. The polypropylene housing construction throughout the assembly ensures uniform chemical resistance, enabling confident processing of demanding sample matrices.
Key Membrane Characteristics
- 1.0 µm polypropylene membrane provides coarse particle removal for prefiltration applications requiring broad chemical compatibility
- 4.9 cm² filtration area in the 25mm diameter format handles particulate-laden samples that would rapidly clog smaller pore sizes
- Hydrophobic surface properties resist aqueous wetting while allowing organic solvents and non-polar solutions to pass efficiently
- Maximum operating pressure of 72.5 psi with 116 psi burst pressure accommodates high-particulate samples and viscous matrices
- Temperature rating to 80°C supports warm solvent filtration and thermal processing requirements in diverse applications
Key Construction Characteristics
- Polypropylene housing material matches membrane composition for consistent chemical resistance throughout the entire flow path
- Double luer lock connections on inlet and outlet ports ensure secure attachment during the processing of pressurized samples
- 25mm diameter configuration balances filtration capacity with compact footprint for manual syringe-driven applications
- Nonsterile format arrives ready for autoclave sterilization at 121°C for 30 minutes when your protocols require sterile operation
The hydrophobic polypropylene membrane maintains structural integrity across diverse chemical environments, delivering reliable prefiltration performance for your demanding applications. You should avoid extended contact with esters, hexane, toluene, benzene, and dichloromethane which may compromise membrane performance over time. When your protocols require sterile filtration, these nonsterile filters accommodate gamma irradiation at 5 kGy for 8 hours or autoclave sterilization, providing flexibility for various laboratory workflows.
