    • A gas supply system is described comprising: a gas capsule (4) enclosed at one end by a pierceable diaphragm (22); a spacer element (20) adjacent the pierceable diaphragm (22), the spacer element (20) having a channel (25) providing access to the pierceable diaphragm (22); a shaft (42) with a piercing tip (38); and a seal (40; 47). The shaft (36), spacer element (20) and seal (40; 47) are arranged so that when the shaft (36) accesses the pierceable diaphragm (22) via the channel (25), the shaft (36) is caused to enter into a sealing engagement with the spacer element (20) via the seal (40; 47) before the piercing tip (38) pierces the pierceable diaphragm (22). In an alternative embodiment (Fig.6), no spacer element (20) is provided and instead a seal (65) is provided in a groove (66) in a wall (32) defining a recess (34) at a position so that when a gas capsule (4) is inserted into the recess (34), the seal (65) enters into a sealing engagement with the gas capsule (4) before the piercing tip (38) of the shaft (36) pierces the pierceable diaphragm (22) enclosing the gas capsule (4).
