Featuring a 0.2 micron hydrophilic polyethersulfone (PES) membrane integrated directly into an all-in-one sample preparation device, this syringeless filter vial combines a self-sampling system, filtration membrane, plunger, and precut septa cap into a single unit. The device consists of an internal insert with a membrane chamber and an external vial. Liquid is placed in the outer vial and dispensed by pressing the inner insert, which pushes the sample through the membrane and leaves it ready for analysis. The polypropylene housing pairs with PTFE and silicone septa, and the light green cap provides color coding by membrane type and pore size.
Key PES Membrane Characteristics
- Naturally hydrophilic polyethersulfone membrane wets out readily for fast, consistent filtration of aqueous samples.
- 0.2 micron pore size provides fine clarification and particulate removal ahead of chromatographic analysis.
- Low protein binding PES chemistry helps preserve analyte recovery and sample integrity.
- PFAS-free verified membrane construction supports trace-level and regulated analytical workflows.
Key Construction Characteristics
- Polypropylene housing with PTFE and silicone septa for broad sample compatibility.
- Precut (pre-slit) septa cap ensures easy, clean transfer of sample into autosamplers.
- 12mm diameter x 32mm height format with a 480ul chamber volume and 450ul filter capacity.
- Compression force of 0.6 bar and a maximum operating temperature of 50 degrees C.
- Nonsterile, supplied 100 per pack with a light green cap.
The single-step filtering process is efficient and fast, reducing sample loss and minimizing the risk of cross-contamination during transfer. With a dead volume as low as 30 microliters, the device helps preserve precious samples while delivering filtrate that is immediately ready for the autosampler. Compatibility with most standard HPLC and UHPLC autosamplers makes it a reliable choice for high-throughput laboratories.
