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 the autosampler.
