Wheaton* Cryule* Vials

Plastic Cryule closures and tubes are both manufactured from medical grade polypropylene which has the same coefficient of expansion. This enhances the leakproof qualities of these vials at changing temperatures. All cryules are designed to withstand temperatures between -196° and 121°C. May be autoclaved.
Also available with silicone ring seals for secure sealing. Caps accept colored inserts for lot coding and a side marking area allows additional product identification.
