Stick to your schedule, not your shelves 
LyoTec™ stoppers have the demonstrated advantage of not adhering to the pressure plates of lyophilization chambers. Pharmaceutical manufacturers using LyoTec stoppers can avoid the risk of lost product, lost time and a chamber clean-up that can result from a lyophilization chamber mishap.

LyoTec stoppers have West FluroTec^® film applied to their top surface. West FluroTec is a fluorocarbon film with a unique low-surface-energy characteristic that helps to eliminate stoppers from sticking to pressure plates and reduces stopper clumping in sterilizers and feeding bowls. The LyoTec stopper’s unique single-vent igloo design is effective in eliminating mechanical twinning, the interlocking of double-vented stoppers during processing.

Converting to LyoTec Stoppers
LyoTec stoppers into production lines may require minimal regulatory review, especially for manufacturers who use an approved West configuration and formulation. Because LyoTec stoppers have a film applied only to the top, non-drug-contact surface, the extent of regulatory review may be dramatically reduced. West’s regulatory experts will help ensure a smooth transition to LyoTec stoppers.
