Thumbnail Filmstrip of Regenerated Cellulose Syringeless Filter Vials, 0.2um, Gray, Nonsterile, 100/Pk Images
Featuring a hydrophilic regenerated cellulose (RC) membrane integrated into a one-step syringeless filtration device, this filter vial combines an autosampler vial, filtration membrane, plunger, and precut septa cap into a single unit. The liquid sample is placed in the external vial and dispensed by pressing the internal insert, pushing it through the 0.2um membrane so the filtered sample is ready to load directly into the autosampler. The low protein binding RC membrane delivers clean clarification of aqueous and organic solvent solutions for reliable downstream analysis.
Key Regenerated Cellulose Membrane Characteristics
- Hydrophilic: Wets out readily for efficient filtration of aqueous and organic solvent solutions.
- Very low protein binding: Preserves analyte concentration and protects sample integrity during preparation.
- Broad solvent compatibility: Resistant to a wide range of solvents for versatile analytical sample prep.
- 0.2um pore size: Provides fine clarification suited to uHPLC and HPLC chromatography sample preparation.
- PFAS-free verified: Manufactured without intentionally added PFAS.
Key Construction Characteristics
- Single-step device: Internal insert with membrane chamber and precut septa cap plus an external vial, eliminating separate syringes, filters, and vials.
- Polypropylene housing: Vial body constructed of polypropylene with PTFE and silicone septa materials.
- Dimensions: 12mm diameter x 32mm height, with a 480ul chamber volume and 450ul filtering capacity.
- Low dead volume: Dead volume as low as 30ul to preserve precious samples.
- Nonsterile, 100 vials per pack, with a gray cap for easy identification.
This syringeless format maintains sample integrity by minimizing transfer steps and the risk of cross-contamination. Operating at a compression force of 0.6 bar and a maximum operating temperature of 50 degrees C, it delivers consistent, repeatable filtration. Compatibility with most standard autosamplers and multi-compressors supports high-throughput workflows without compromising results.
