Claim 0:
1. A lyophilization syringe configured for both the in situ lyophilization of an initial product and the reconstitution and dispensing of said product in lyophilized form, said syringe comprising:
a. an elongate central barrel characterized by (i) a plurality of distinct, resiliently deformable lateral walls joined together to define an exterior surface and a hollow interior bore configured to retain both said initial product and said product in lyophilized forms, (ii) an open distal tip configured to engage a hypodermic needle assembly; and (iii) an open proximal end configured to receive a sealing piston and dispensing plunger;
b. wherein said central barrel has a non-circular cross-section;
c. further wherein insertion of said syringe into a well arranged on a top side of a thermal lyophilization block made from a single piece of heat conductive material that is sized and shaped to closely accommodate said syringe causes said lateral walls to deform and said exterior surface to be compressed into substantial intimate contact with an inner wall of said well.
