The syringe (20) consists of a body (21) and nozzle (22) made from a supple elastomer-based material that is suitable for autoclaving., The body is cylindrical in shape, containing a metal piston (23), and is contained inside a removable rigid plastic sleeve (30) when in use. After use the sleeve is opened by means of two catches (32) and a lengthwise hinge (31), allowing any residues (10a) of the hardened product to be extracted from the body and nozzle. |
