Thumbnail Filmstrip of PFAS-Free Nylon Syringeless Filter Vials, 0.45um, 32mm, Blue, Nonsterile, 100/Pk Images
Featuring a hydrophilic Nylon membrane integrated into an all-in-one self-sampling vial, this syringeless filter vial clarifies aqueous and organic solvent solutions in a single press-and-filter step. The 0.45um membrane is housed in a 32mm format device measuring 12mm in diameter by 32mm in height, combining the membrane, plug vial, and pre-slit cap into one consumable that replaces the separate syringe, syringe filter, glass vial, and cap. Liquid placed in the outer vial is pushed through the membrane by pressing the inner insert, leaving the filtrate ready for direct autosampler injection. This device is PFAS-free verified and supplied nonsterile in packs of 100.
Key Nylon Membrane Characteristics
- Naturally hydrophilic, making it well suited to aqueous and alcoholic media without the need for prewetting.
- 0.45um pore size delivers reliable clarification of samples ahead of HPLC and chromatography analysis.
- Broad compatibility with aqueous and organic solvent solutions for versatile sample preparation.
- PFAS-free verified construction supports trace-level analytical workflows where fluorinated background contamination must be avoided.
Key Construction Characteristics
- All-in-one vial built from polypropylene with PTFE and silicone septa, with a pre-slit cap for easy and clean sample transfer.
- 32mm format device measuring 12mm diameter by 32mm height, compatible with most standard autosamplers and multi-compressors.
- 480ul chamber (fill line) volume with a 450ul filtering capacity and 30ul dead volume.
- 0.6 bar (8 psi) compression force and a maximum operating temperature of 50C.
- Supplied nonsterile in a pack of 100 in a blue color code.
The single-step filtering process reduces sample loss and consolidates multiple consumables into one device, helping maintain sample integrity from preparation through injection. By squeezing the sample directly through the membrane and into an autosampler-ready vial, it streamlines preparation while delivering consistent, repeatable clarification.
