Polytetrafluoroethylene (PTFE) Syringe Filters - SF18239

When you're processing small volumes of samples with coarse particles, you need low holdup volume and broad chemical resistance. These 5.0µm PTFE filters combine just 10µl sample retention with the chemical compatibility to handle aggressive solvents, acids, and bases. The compact 13mm diameter removes large particles and precipitates while pre-sterilized packaging ensures contamination-free handling. Polypropylene housing withstands pressures up to 87psi across diverse chemical systems.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively prefilters organic solvents, acids, and bases without chemical interaction
• Coarse 5.0µm pore size removes large particles, precipitates, and visible contaminants from limited samples
• Pre-sterilized by gamma irradiation ensures contamination-free handling for critical laboratory applications
• Broad chemical resistance from strong carbon-fluorine bonds maintains stability in aggressive solvent systems
• Membrane thickness of 80-140µm optimizes flow characteristics for rapid processing of small volumes

Key Construction Characteristics

• Polypropylene housing provides excellent chemical compatibility with organic and inorganic solvents
• Small 13mm diameter with 1.09cm² filtration area, ideal for precious samples and microscale applications
• Ultra-low holdup volume of 10µl maximizes recovery of expensive or irreplaceable analytical samples
• Luer-Lok/Luer Slip dual connection design accommodates various syringe types and volumes

You recover more of your precious samples with just 10µl holdup volume - important when working with limited-volume reagents or expensive analytical standards. Pre-sterilized packaging means contamination-free handling without autoclaving preparation, and you can process samples at temperatures up to 60°C. The 87psi burst pressure provides reliable performance across aggressive chemical applications, while the coarse pore structure quickly processes samples that would clog finer membranes.

Hydrophobic

• Small-Volume Prefiltration - Removes coarse particles from limited samples, protecting expensive downstream 0.22µm filters from premature clogging
• Microscale Sample Processing - Prefilters cell culture reagents and growth factors, where a 10µl holdup volume conserves precious limited volumes
• Precipitate Removal - Clarifies crystallized solutions from organic synthesis, where aggressive solvents require chemically resistant filtration
• Cell Culture Clarification - Removes cellular debris and large particulates from culture supernatants before downstream fine filtration steps
• Pharmaceutical Development - Prefilters small-volume drug formulations and API solutions in early-stage development with minimal sample loss
• Biological Extract Processing - Clarifies tissue homogenates and cell lysates, removing coarse particulates before analytical instrumentation
