Abstract
A method and an apparatus for the storage and transfer of a lyophilisate, oncolytic, mutagenic, or other prescription is disclosed. An ampule prior to its being sealed has an orifice at one end for the addition of the lyophilisate, for example or one component of a multi-component mixture. After placement of the lyophilisate, the orifice is sealed. The ampule has a body portion formed with flexibly deformable walls and with the sealed orifice defines a blind bore. An opening of the ampule is also included and has a tapered section adapted to frictionally fit over a taper of a male luer-type fitting commonly found on syringes and needleless cannulas. The opening is protected by a frangible cap integrally formed during manufacture. By removing the cap and docking the opening with a syringe, liquid enters the ampule for mixing with the dry contents in the ampule without ambient air.
