V Vial 2ml Grad 20-400 Cap TFE Lnr

Clear graduated glass vials with solid top black phenolic caps Teflon® faced 14B rubber liner Screw cap attached Heavy wall construction for variety of applications Conical interior bottom provides downward drainage Made from clear and amber borosilicate glass Available with solid and open top screw cap or serum finish Vials are produced with a rough, ground bottom but, due to improvements in manufacturing, we are now able to offer this NextGen 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. Premium style packaging minimizes particulate contamination of the vials. 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 Wheaton Micro Kit (Thomas No. 0914R41). They are also used in the biochemical, pharmaceutical and radiochemical industries. Additional applications and techniques for using Wheaton V-Vials include anaerobic reactions; derivatization; micro mixing; catalytic hydrogenation; extraction; packaging; centrifugation; homogenization; radiosynthesis; concentration; and hybridization.
