Glass Vials are manufactured from Wheaton 180 low potassium borosilicate glass that conforms to ASTM Type I, Class A requirements. Critical manufacturing tolerances ensure reliable, consistent results for 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 writing.
