E-C Sample Vials Without Screw Caps, 8mL

These economically priced sample vials are conveniently packed in two shrink-wrapped packs of 100 vials. This packaging reduces contamination from corrugated material found in traditional packaging. The clear vials are manufactured from Wheaton 33 low extractable borosilicate glass that conforms to ASTM Type I, Class A and USP Type I requirements, and the amber vials are manufactured from Wheaton 320 amber glass that conforms to USP Type I requirements to protect light-sensitive samples. It is suggested to use 14B rubber lined caps for aqueous samples and PTFE faced 14B rubber lined caps for organic samples. Caps can be purchased separately.
