Choose Thermo Scientific™ SureSTART™ Total Recovery Glass Screw Top Microvials, Performance Level 3, when you need to maximize the injection volume for <2 mL samples. Available in clear and amber glass, this one-piece Total Recovery microvial has a very low residual volume due to a specially-shaped deep and narrow inner reservoir which collects the liquid in the base so that compatible autosamplers can collect all but 1-2 ?L of sample while having a total sample volume of 1.2 mL and a residual volume of 1 ?L. The outer dimensions for these vials are 12x32 mm. These Performance Level 3 vials are designed to protect your most valuable samples and deliver consistent, reproducible results for your most demanding analyses.
