Wheaton Lyophilization Ampules, Bottles & Vials

Long term storage stability of biological materials has made this a preferred technique at biochemical / biotech and pharmaceutical companies and at universities and medical schools for samples such as blood plasma, vaccine, serum, tissue samples, enzymes and microbial cultures. The food /beverage industry also uses this technique.

The primary containers used for lyophilization tray drying are serum bottles, serum vials and to a much lesser extent ampules. The prime accessory is the 2 or 3 leg stopper 1 which has been designed to sit on the top of the container during the lyophilization process 2, and is inserted 3 during the stoppering step in the process. The closure (aluminum seal or threaded cap) is then applied 4. The split stopper is utilized when the dried product is sensitive to air or moisture and needs a rapid seal. Not all freeze dried materials are this sensitive or will require use with the split stopper. WHEATON can provide all the above mentioned products as well as crimpers to give your containers a secure seal.

This section of the catalog includes most products used in freeze drying applications. Although these products appear in other sections of the catalog, we hope you find it convenient to have the products commonly used in the lyophilization process located in one section of the catalog.
