Description:
Wheaton 986546 20mL Glass Scintillation Vials with PE Cone Seal Lined Urea Caps. These 20mL vials are the original and the standard by which counting vials are judged. Wheaton "180" low-potassium glass (meets ASTM Type I Class A and USP Type I standards) and critical manufacturing tolerances ensure reliable, consistent results in scintillation counting. Vials load properly into counting machines without jamming or breaking. Background counts are consistent and low; ultraviolet transmission is high. White caps fit tightly to avoid solubilizer fumes in the laboratory and have tops suitable for marking. Dimensions: 28 mm x 61 mm. 500/case.
