Choose Thermo Scientific™ 1.5 mL Total Recovery Glass Snap Top Microvials, Performance Level 3, when you need to maximize the injection volume for <2 mL samples. This one-piece, 12x32 mm Total Recovery microvial has a very low residual volume due to a specially shaped deep and narrow inner reservoir. This configuration collects the liquid in the base so that compatible autosamplers can inject all but 1-2 ?L of sample while having a total sample volume of 1.2 mL and a residual volume of 1 ?L. These are Performance Level 3 vials, which means they are designed to protect your most valuable samples and deliver consistent, reproducible results for your most demanding analyses.
