Polytetrafluoroethylene (PTFE) Syringe Filters - SF18010

When you're working with small analytical samples where every microliter counts, you need both low holdup volume and contamination-free handling. These 0.45µm hydrophilic PTFE filters combine just 10µL sample retention with the chemical resistance to handle aggressive solvents and aqueous solutions without pre-wetting. The 13mm diameter clarifies particles from your samples while preserving dissolved analytes, and pre-sterilized packaging means contamination-free handling right out of the package. The polypropylene prefilter protects the PTFE membrane from premature clogging when processing particulate-laden samples.

Key PTFE Membrane Characteristics

• Hydrophilic surface modification eliminates alcohol pre-wetting, letting you process aqueous samples immediately
• 0.45µm pore size removes particles and suspended solids while preserving dissolved analytes for analytical accuracy
• Low protein binding minimizes sample loss when filtering protein solutions and biological samples
• Broad chemical resistance handles both aqueous solutions and organic solvents across diverse analytical workflows
• Membrane thickness of 80-140µm provides structural stability while maintaining efficient flow through the membrane

Key Construction Characteristics

• 10µL holdup volume maximizes recovery of precious analytical samples and expensive reagents
• Pre-sterilized packaging provides contamination-free handling without autoclaving preparation
• 13mm diameter with 1.09cm² filtration area efficiently processes small to medium sample volumes
• Integrated polypropylene prefilter captures large particles before they reach the PTFE membrane, extending filter life

Pre-sterilized packaging means you can start filtering immediately without preparation steps, saving time when processing multiple analytical samples. You recover virtually all of your sample with just 10µL holdup volume - critical when working with expensive standards or limited-volume specimens. The 87psi burst pressure provides reliable performance across diverse analytical applications, and the 21.75psi bubble point confirms consistent pore structure for reproducible clarification results.
