London County Council Pattern Chloroform Inhaler
Date of manufacture:
Krohne & Sesemann, London
This modification of the original Junker's inhaler has a dual bottle to avoid accidental delivery of liquid chloroform to the patient in the event of miss connection of the two rubber tubes. Filling is achieved by unscrewing the appropriate bottle.
