Thumbnail Filmstrip of Regenerated Cellulose Syringeless Filter Vials, 0.45um, 32mm, Black, Nonsterile, 100/Pk Images
Featuring a one-step syringeless filtration design that integrates a self-sampling system, hydrophilic regenerated cellulose (RC) membrane, and a precut septa cap into a single device, these filter vials streamline sample preparation for chromatography. The sample is placed in the outer vial and dispensed by pressing the inner insert, pushing liquid through the 0.45um membrane so the filtered sample is ready to load directly into an autosampler. Each device offers a 480ul chamber volume and a 450ul filter capacity, with a low 30ul dead volume that preserves precious samples. The vial is supplied in black, nonsterile, and packaged 100 per pack.
Key Regenerated Cellulose Membrane Characteristics
- Naturally hydrophilic, ideal for filtering aqueous and polar samples without pre-wetting
- Very low protein binding to maximize analyte recovery and sample integrity
- Resistant to a wide range of solvents for broad sample compatibility
- 0.45um pore size delivers clarification and particulate removal ahead of HPLC and UHPLC analysis
Key Construction Characteristics
- Polypropylene housing with PTFE and silicone septa
- Precut septa cap ensures easy, clean sample transfer and direct autosampler loading
- 32mm vial format with a 480ul chamber volume and 450ul filter capacity
- Low 30ul dead volume and a 0.6 bar compression force for efficient single-step filtering
- Withstands a maximum operating temperature of 50C; supplied nonsterile, 100 per pack
This all-in-one vial replaces the separate syringe, syringe filter, glass vial, and cap used in conventional workflows, reducing waste and the risk of cross-contamination. The single-step press-and-filter process delivers fast, reproducible sample clarification while preserving sample integrity for accurate downstream analysis.
