As all freeze dryer users would know, filling of vials that are to be lyophilized has some problems that are somewhat unique. The stopper is placed on top of the vial and is ultimately seated in the lyophilizer. As a result the contents of the vial are subject to contamination until they are actually sealed.
In the FDA Inspection guide (Lyophilization of Parenteral 7/93) it is highlighted that “in the transport of vials to the lyophilizer, since they are not sealed, there is concern for the potential contamination”.
A suitable container system must be chosen for the product. The most common product containers are flasks, vials and trays. If possible, it is advisable to pick a container that keeps the maximum thickness of the product to less than ¾” (or 2 cm).
These containers are subject to the following matters:
Product loss: fluffy dry powder flies out during (or after) the freeze-drying cycle
Contamination: dry powder contaminates the freeze dryer and endangers operators
Cleaning and cleaning validation
