Wheaton® 0.3mL V-Vials, Borosilicate Glass, 13-425, PTFE Faced Rubber Liner, case/12

High Recovery Vials, 0.3mL or 0.01oz, Clear, 20mm Finish with PTFE /14B Rubber liner, Type I Borosilicate Glass.
V-Vials feature a smooth and clear bottom instead of a rough ground bottom. Grinding has been eliminated from their manufacturing, to reduce the chance for particulates entering the vial. These exceptionally sturdy vials have a conical interior bottom that allows for maximum retrieval of content by syringe or micropipette.

V Vials can be used for small-scale reactions, centrifugation, storage and shipping. Clear V Vials are manufactured from 33 low extractable borosilicate glass that conforms to ASTM Type I, Class A and USP Type I requirements to safeguard against a change in product pH caused by alkali, which can be extracted by ordinary glass. Amber V Vials are manufactured from 320 low extractable borosilicate glass that conforms to ASTM Type I, Class B and USP Type I requirements. V-Vials are used for small-scale reactions with a Micro Kit. They are also used in the biochemical, pharmaceutical and radiochemical industries.

Additional applications and techniques for using V-Vials include anaerobic reactions; derivatization; micro mixing; catalytic hydrogenation; extraction; packaging; centrifugation; homogenization; radiosynthesis; concentration; and hybridization.
