Feature

Made of low borosilicate glass, the tube features good resistance to common weak acid and alkali. It maintains uniform wall thickness and high clarity with minimal internal bubbles and impurities. The flat base enables the tube to stand independently on flat surfaces, and one end is permanently sealed. The open end is smoothly processed without sharp burrs. Outer diameter ranges 5.0–8.0 mm, while length and wall thickness are available for custom configuration.

Application

It is used for static storage of trace liquid and solid samples in laboratory testing, and serves as miniature sample containers for analytical inspection, aroma and reagent preservation.
