Verex Filter Vials for Filtration and Analysis

Sample Prep Simplified – Push to Filter, Ready to Inject!

Verex filter vials are designed to provide simple and rapid sample preparation by incorporating a syringe, filtration membrane, vial, and cap/septa all into one product. Each filter vial is comprised of two parts: the external vial and internal plunger with an integrated filter and cap with a pre-slit PTFE/Silicone septa. Simply, dispense your sample into the external vial and compress the internal plunger to filter. This produces a particulate-free sample ready for analysis. Verex filter vials are a standard 12 x 32 mm vial and can be easily loaded into an autosampler.
