Featuring an all-in-one syringeless filtration design, these filter vials integrate a self-sampling system, hydrophobic PTFE membrane, plunger, and a precut septa cap into a single disposable device. The internal insert holds a membrane chamber with a 480 microliter chamber volume and a 450 microliter filtering capacity, while the 0.45um PTFE membrane delivers reliable clarification of aqueous and organic solvent samples. Liquid placed in the outer vial is dispensed by pressing the inner insert, pushing the sample through the membrane so it is ready to load directly into an autosampler.
Key PTFE Membrane Characteristics
- Hydrophobic PTFE membrane delivers superior chemical resistance and broad solvent compatibility
- Chemically and biologically inert structure preserves sample integrity
- 0.45um pore size suited to clarification and particulate removal ahead of analysis
- Well matched to aqueous and organic solvent solutions in chromatography workflows
Key Construction Characteristics
- Polypropylene body with PTFE membrane and silicone septa
- Precut (pre-slit) septa cap ensures easy and clean sample transfer
- 480 microliter chamber volume and 450 microliter filtering capacity with dead volume under 30 microliter
- 12 mm diameter by 32 mm height profile compatible with most standard autosamplers and multi-compressors
- Red cap, nonsterile, supplied 100 per pack
This single-step device replaces a separate syringe, syringe filter, glass vial, and cap, reducing waste and sample preparation time. The plunger-driven design minimizes sample loss while maintaining sample integrity from filtration through analysis. A maximum operating temperature of 50C and a low compression force of 0.6 bar support consistent, repeatable performance.
