PES Syringeless Filter Vials, 0.45um, PES Membrane, Dark Green, PFAS-Free, Nonsterile, 100/Pk
GVS SKU: MV32ANPPS004WC01PF

Featuring a hydrophilic polyethersulfone (PES) membrane with a 0.45um pore size, this PFAS-free verified syringeless filter vial integrates an auto-sampler vial, filtration membrane, plunger, and pre-cut septa cap into a single one-step sample preparation device. Sample is placed in the external vial and dispensed by pressing the internal insert, pushing the liquid through the membrane so the filtered sample is ready for analysis. The dark green color codes the 0.45um PES variant for fast visual identification, and each unit measures 12mm diameter by 32mm height with a chamber volume of 480ul, a filtering capacity of 450ul, and a dead volume of just 30ul. Supplied nonsterile, 100 per pack.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic media designed to remove particulates from aqueous solutions, buffers, and culture media
• Low protein and drug binding characteristics that help maximize recovery of critical sample components
• High strength and durability suited to aggressive handling and automated workflows
• Broad chemical compatibility across acids, bases, and a wide range of solvents
• PFAS-free verified construction for trace-level PFAS analysis and confidence in analytical results

Key Construction Characteristics

• Polypropylene housing with PTFE and silicone septa for chemical resistance and a clean seal
• Pre-slitted septa cap that ensures easy, clean sample transfer and compatibility with most auto-samplers and multi-compressors
• Compression force of 0.6 bar (8 psi) and a maximum operating temperature of 50 degrees C (120 degrees F)
• Nonsterile, supplied 100 per pack, dark green color coded to the 0.45um PES membrane

The all-in-vial design reduces sample loss by eliminating transfer steps between separate syringes, filters, and vials, helping preserve precious samples and reduce the risk of cross-contamination. The 30ul dead volume and 450ul filtering capacity support work with small or costly sample volumes, while the integrated membrane delivers consistent clarification for reliable downstream chromatography. Filtered samples are ready to load directly into HPLC and UHPLC auto-samplers.
