20 mL Scintillation Vials

United Scientific Scintillation Vials are designed for reliable performance in liquid scintillation counting, sample storage, and analytical laboratory workflows. Made from borosilicate glass that meets ASTM Type I Class A and USP Type I standards, these 20 mL vials provide dependable clarity, chemical resistance, and consistency for sensitive applications.

Precise manufacturing tolerances help the vials load smoothly into standard liquid scintillation counting equipment, reducing the risk of jamming or breakage during routine use. They’re engineered to provide low, consistent background counts and high ultraviolet transmission, supporting accurate, repeatable counting performance.

Choose from attached or unattached cap styles with polypropylene or white urea caps and multiple liner materials to match your application needs. Secure-fitting caps can be labeled for easy sample identification, and each pack is supplied with a Certificate of Conformity for quality documentation.
