LyoTec® Stoppers

Stick to Your Schedule, Not Your Shelves™

West LyoTec® stoppers have West FluroTec® film applied to their top surface, which helps eliminate stoppers from sticking to pressure plates and reduces stopper clumping in sterilizers and feeding bowls. Stopper performance in the lyophilization chamber is critical, whether processing is done in the pharmaceutical manufacturer's facility or at a contractor’s site.

The unique LyoTec single-vent igloo stopper design is effective in eliminating mechanical twinning, the interlocking of double-vented stoppers during processing.

LyoTec stoppers bring an added measure of safety to any lyophilization process:

  • For cytotoxic drug products, a lyophilization chamber incident can trigger an even more expensive and dangerous environmental cleanup.
  • For processing inside a barrier isolator, using LyoTec stoppers can help prevent a costly cleanup that breaches the sterile environment.

Because the LyoTec stopper only has film applied to the top, non-drug contact surface, integrating LyoTec stoppers into production lines may require minimal regulatory review, especially for manufacturers who use an approved West configuration and formulation.
