Wheaton Glass Serum Vials

Wheaton glass serum vials are manufactured from low extractable borosilicate glass conforming to ASTM Type I, Class A and USP Type I requirements. The blowback feature in the neck and specially designed bottom radius of these glass serum vials provide the added strength important for lyophilization applications (freeze drying & dehydration). Wheaton glass serum vials are packaged in shrink- wrapped modules to greatly reduce the chance of particulate contamination. Crimp seal closures are sold separately. Glass serum vials are available in both clear and amber glass colors.
