Thumbnail Filmstrip of PES Syringeless Filter Vials, 0.2um, 32mm, PFAS Free, Light Green, Nonsterile, 100/Pk Images
Featuring a hydrophilic polyethersulfone (PES) membrane with a 0.2um pore size, this syringeless filter vial integrates a self-sampling system, membrane, cap, and precut septa into a single one-step sample preparation device. The sample is placed in the outer vial and dispensed by pressing the inner insert, pushing liquid through the membrane so the filtered sample is immediately ready for the autosampler. This PFAS Free verified format eliminates the need for separate syringes, syringe filters, vials, and septa while preserving sample integrity.
Key PES Membrane Characteristics
- Naturally hydrophilic polyethersulfone media for spontaneous wetting with aqueous samples.
- Low protein binding for high sample recovery and reliable analytical results.
- Broad chemical compatibility across acids, bases, oxidants, solvents, and fine chemicals.
- 0.2um pore size suited to fine clarification and removal of sub-micron particulates ahead of analysis.
- PFAS Free verified construction for trace and PFAS-sensitive workflows.
Key Construction Characteristics
- Polypropylene housing with PTFE and silicone septa for chemical resistance and clean sample transfer.
- 32mm diameter format with a Light Green color-coded cap for quick membrane and pore identification.
- Precut septa cap allows easy, clean transfer of filtrate directly into the autosampler.
- Supplied nonsterile, 100 vials per pack.
This syringeless design delivers a rapid single-step filtration that reduces sample loss and minimizes hand stress during high-volume sample preparation. The PES membrane maintains low protein binding and high recovery, helping protect downstream instruments and improve the consistency of analytical results.
