Thumbnail Filmstrip of Nylon Syringeless Filter Vials, 0.45um, 12mm, Precut Septa Cap, Blue, Nonsterile, 100/Pk Images
Featuring a hydrophilic Nylon 66 membrane sealed within a one-step sample preparation device, these syringeless filter vials integrate the autosampler vial, filtration membrane, plunger, and precut septa cap into a single unit. The sample is placed in the outer vial and dispensed by pressing the inner insert, pushing the liquid through the 0.45um membrane so the filtered sample is ready to load into an autosampler. Each vial is built on a polypropylene body measuring 12mm in diameter by 32mm in height, with a chamber volume of 480ul and a filtering capacity of 450ul.
Key Nylon Membrane Characteristics
- Naturally hydrophilic Nylon 66 membrane requires no prewetting for aqueous samples
- 0.45um pore size clarifies and removes particulates from samples prior to analysis
- Well suited to clarification of aqueous and organic solvent solutions
- Ideal for HPLC and chromatography sample preparation
- Low dead volume of less than 30ul helps preserve precious samples
Key Construction Characteristics
- Polypropylene vial body with PTFE and silicone septa materials
- Precut (pre-slit) septa cap ensures easy and clean transfer of sample
- Chamber volume of 480ul and filtering capacity of 450ul
- Withstands a maximum operating temperature of 50C
- Nonsterile, supplied 100 per pack in a blue color code
The integrated design replaces separate syringes, syringe filters, glass vials, and caps, reducing waste while increasing sample integrity. Compatible with most standard autosamplers and multi-compressors, these vials deliver consistent, reliable filtration in a rapid single step. The verified PFAS-free construction supports sensitive analytical workflows where trace contamination must be avoided.
