Abstract:

The monomer transfer device of this invention includes a syringe adapted to receive an ampule and adapted for connection to a vacuum source such that with the ampule open within the syringe body, the monomer is vacuumed out of the ampule and into the mixing container. Alternative embodiments accept an unbroken ampule and include an offset designed to break the ampule at its predetermined break point to permit the contents of the ampule to be vacuumed from the ampule and transferred to the mixing container. A small mesh filter or screen may be included to any of the ampule before it reaches the mixing container. Once the ampule is inserted into the syringe, an end cap is connected to close the syringe and maintain any fumes within the syringe. In the alternative embodiments, the end cap acts to force the ampule against the offset so as to cause the ampule to break.
