Thumbnail Filmstrip of PVDF Syringeless Filter Vials, 0.2um, 32mm, Precut Septa Cap, Nonsterile, Yellow, 100/Pk Images
Featuring a hydrophilic 0.2um PVDF membrane sealed within a polypropylene insert, this syringeless filter vial integrates filtration and sample collection into a single one-step device. The liquid is placed in the outer vial and dispensed by pressing the inner insert, pushing the sample through the membrane so the filtered sample is ready for autosampler analysis without a separate syringe, syringe filter, glass vial, or cap. With a 480uL internal chamber volume and 450uL filtering capacity, it streamlines small-volume sample preparation while maintaining sample integrity.
Key PVDF Membrane Characteristics
- Naturally hydrophilic 0.2um PVDF membrane wets readily with aqueous samples for consistent filtration.
- Low protein binding helps preserve analyte recovery in sensitive chromatographic workflows.
- Broad chemical compatibility supports filtration of a wide range of aqueous and many organic sample matrices.
- 0.2um rating delivers fine clarification and microbial reduction for clean, particle-free filtrate.
Key Construction Characteristics
- Polypropylene housing with an internal insert that holds a sealed membrane chamber and a precut septa cap.
- Cap incorporates PTFE and silicone septa with a pre-slit design for easy, clean autosampler access.
- 32mm vial diameter compatible with most standard autosamplers.
- 480uL internal chamber volume and 450uL filtering capacity.
- Nonsterile, yellow cap color coded, supplied 100 per pack.
This all-in-one design replaces multiple consumables, reducing waste and preparation steps while delivering reliable, repeatable filtration. The pre-slit septa supports clean sample transfer directly into the autosampler, helping protect sample integrity from filtration through analysis.
