Storage Vial

Our Mastelf Storage Vials are designed for safe and reliable storage of liquids, solvents, and reagents in laboratory environments. Manufactured from USP Type 1 borosilicate glass or soda-lime glass, these vials provide flexible solutions for both high-precision and routine applications.

Available in both clear and amber glass, our storage vials are suitable for a wide range of sample types, including light-sensitive liquids. The selection of material depends on the chemical nature of your sample, especially whether the solution is inert or reactive.

In analytical workflows, storage vials are also widely used for sample collection, preparation, and transfer prior to autosampler injection, ensuring clean and stable sample handling.
