A process for lyophilizing bulk solutions of products in which liquid product is poured into bottomless trays, frozen and dried.

Lyophilization of bulk pharmaceuticals

A pre-filled chamber having a piston plug at one end and a stopper at the other end. The chamber is filled with a powdered medicament that is to be intermixed with a diluent in a container. Rotatable attachments join the chamber containing the powder with a receptacle on the container. The powdered medicament is expelled from the chamber by the force of a plunger acting on the piston plug. The stopper at the end of the chamber containing the powder serves as a mounting for a piercing tip which breaks a membrane over the neck of the container allowing fluid connection between the chamber and the container and transferral of the powdered medicament from the chamber to the container.
