Thomson SINGLE StEP® Filter Vials (patent pending) are designed to speed up sample prep and analysis. The plunger filter with 0.45uM Teflon membrane nestles into the vial while simultaneously filtering and readying the sample for any Autosampler.This is a SINGLE StEP® process that minimizes any loss of sample and requires no multiple step transfers. Pre-slit caps ensure a no-hassle, clean aliquot withdrawal. No more breakage of expensive needles, coring problems on the HPLC or Mass Spec. Thomson SINGLE StEP® Filter Vials are compatible with most standard Autosamplers; such as Agilent® and Waters®.
