West LyoTec® rubber stoppers have the West FluroTec® film applied to their top surface, which prevents the stoppers from sticking to the pressure plates. The unique West LyoTec® igloo stopper design effectively prevents mechanical twinning. Because the FluroTec® coating is applied only to the top, non-medicated surface, the integration of LyoTec® rubber stoppers into production lines may require minimal regulatory review, especially for manufacturers using an approved West configuration and formulation.
LyoTec® stoppers provide an additional level of safety for any freeze-drying process:
-
For cytostatics, an incident in the lyophilization chamber can trigger an even more expensive and dangerous environmental cleanup.
-
When processed in a barrier isolator, the use of LyoTec stoppers can prevent costly cleaning that breaches the sterile environment.
