Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18159
Hydrophilic PTFE at 5.0μm gives you coarse prefiltration for aqueous samples without pre-wetting hassles. You're removing large particles, debris, and gross contamination before fine filtration steps—protecting your expensive membranes and analytical equipment downstream. This gamma-sterilized 25mm format arrives ready for contamination-sensitive work, so you process immediately without preparation delays. The 4.08cm² filtration area handles your standard sample volumes while maintaining rapid flow through high-particulate matrices. For pharmaceutical and biotechnology prefiltration where you need both clean handling and PTFE's chemical resistance, you're getting sterile coarse filtration in a ready-to-use aqueous format that simplifies your workflow.
Key Polytetrafluoroethylene Membrane Characteristics
- Specialized hydrophilic treatment eliminates pre-wetting requirements, enabling immediate processing of aqueous biological samples, pharmaceutical solutions, and mixed media systems
- Outstanding chemical inertness maintains stability when exposed to diverse laboratory chemicals while providing compatibility with both organic solvents and aqueous solutions
- Large 5.0µm pore openings efficiently capture coarse particles and debris while maintaining rapid flow rates for high-throughput processing of aqueous samples
- Extremely low protein binding preserves sample composition and prevents fouling during processing of complex biological and pharmaceutical formulations
- Superior mechanical durability withstands high differential pressures without compromising coarse filtration performance or membrane reliability under challenging conditions
Key Construction Characteristics
- Lightweight polypropylene housing construction delivers comprehensive chemical compatibility and maintains dimensional stability across temperature ranges up to 80°C
- Standard 25mm diameter with 4.08cm² filtration area optimizes yield by providing maximum membrane surface for coarse filtration applications
- Double luer lock interface ensures secure connections and prevents leakage during processing of diverse aqueous samples and analytical protocols
- Structural integrity provided by a 116psi burst pressure rating ensures reliable operation under demanding laboratory conditions and elevated pressures
When you need prefiltration that protects expensive downstream equipment, this 5.0μm PTFE filter gives you coarse particle removal without pre-wetting delays. The large pore size maintains high flow rates through particulate-heavy samples—you're not fighting clogging on the first filtration stage. Since it arrives gamma-sterilized, you're processing contamination-sensitive samples right away while PTFE's chemical resistance handles diverse solvents. For prefiltration work where rapid throughput and clean handling both matter, you're getting reliable coarse particle removal in a sterile format that eliminates preparation steps and keeps your fine filters working longer.
