These small reaction vials have an internal cone designed to make small-sample collection and handling easy and convenient. The cone feature is particularly useful for removing small quantities of sample with a syringe.

• Extra thick glass wall magnifies the sample ideal for observing chemical reactions
• Amber vials are light-sensitive to well protect the compounds

These vials are ideal for residue isolation, derivative preparation, maximum sample retrieval, moisture protection, sample storage, purification, precipitations, centrifugations and solvent separations.
