Thumbnail Filmstrip of PTFE Syringe Filters, 1.0um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - SF18275
Featuring hydrophobic PTFE membrane technology with 1.0µm pore size in pre-sterilized packaging for precise filtration of small-volume samples in aggressive solvent systems. Compact 13mm diameter filters minimize sample loss with just 10µl holdup volume while ensuring effective removal of fine particulates. Polypropylene housing construction maintains chemical compatibility at pressures up to 87psi for reliable sterile microscale applications.
Key Polytetrafluoroethylene (PTFE) Membrane Characteristics
- Hydrophobic membrane design effectively filters organic solvents, acids, and bases without chemical interaction
- Precision 1.0µm pore size removes fine particles, suspended solids, and microbial contaminants from samples
- Pre-sterilized by gamma irradiation ensures contamination-free filtration for critical aseptic applications
- Exceptional chemical resistance from strong carbon-fluorine bonds maintains stability in caustic environments
- Membrane thickness of 80-140µm optimizes retention efficiency while maintaining flow for small volumes
Key Construction Characteristics
- Polypropylene housing ensures broad chemical compatibility with organic and inorganic solvents
- Small 13mm diameter with 1.09cm² filtration area, ideal for precious samples and limited-volume applications
- Ultra-low holdup volume of 10µl maximizes recovery of expensive or irreplaceable analytical samples
- Luer-Lok/Luer Slip dual connection system accommodates various syringe sizes for versatile operation
SF18275 filters optimize your small-volume sterile sample preparation with a 20ml flow rate that balances thorough particle removal with practical throughput. Pre-sterilized packaging eliminates preparation steps while your samples maintain complete sterility at operating temperatures up to 60°C. Bubble point verification at 4.35psi using absolute ethyl alcohol confirms consistent membrane pore structure for reproducible sterile filtration results.
