Fluotec Mk. Fluothane Vaporiser
ED.CS.2025.35.182
Metal fluothane (halothane) vaporiser. Heavy cylindrical body with a circular glass window on one side with a line m arked 'full', and a larger protruding port with a metal screw stopper. The body of the vaporiser is marked 'Flouthane, keep upright when chraged'. At the top of the cylander is a circular dial, the centre of which is red and inscribed '% fluothane'. Can be turned between 'off' and 4.0. Connected to this is a large double ended valve, which has a black metal plaque on the top reading'Fluotec Cyprane Ltd' along with a serial and patent number. Attached by a chain at the top of the vaporiser is a plastic card showing a chart of standard deviations at lower flows.
Designed by Bill Edmondson, who set up his own company, Cyprane, at Keighley, Yorkshire for manufacture. Engineered by ex-BOC Design Engineer Wilfred Jones. A safe temperature compensated vaporizer for the potent agent halothane and the first such vaporizer to be widely accepted. Earlier short-lived Mk 1s were identical apart from minor details such as the fixing of the vapour control dial to the rotational "Barrel", the Mk 2 being a safer version. All Mk 1s were converted to Mk2.
