Chloroform chamber for Clover's inhaler


Chloroform chamber for Clover's chloroform inhaler, by Coxeter

Joseph Thomas Clover (1825-1882) invented the inhaler with which this chloroform chamber was used in 1862. The Clover inhaler was never popular despite Clover demonstrating its successful use for regulating dosage – incorrect doses of chloroform proved to be lethal.

Using a syringe, 2.4 ml of liquid chloroform was injected into the chamber then heated by a vaporizer, which was attached to bellows that could pump sixteen litres of air at a time. This created a concentration of 4.5 per cent chloroform in air, enough to anaesthetise a patient within four minutes.
