Product Description
Stopper-sealing ampules after freeze-drying is quicker and simpler than flame sealing. These two-leg stoppers sit partly inserted during lyophilization to let vapor escape, then press fully home to close the ampule when the cycle is complete. They are a practical companion to small-volume lyophilization ampules.
This listing is for Wheaton catalog number W651450: Lyophilization Ampule Stopper, 11 mm, Case of 144. They are made from gray butyl rubber in an 11 mm size to fit compatible lyophilization ampules, and they are autoclavable for sterile processing. Each case contains 144 stoppers, a practical quantity for routine freeze-drying work. Keep a supply on hand alongside your ampules so each freeze-drying run can be closed promptly. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
