Massive Ducretet Gas Discharge Tube – Paris c1890
Short Description
This massive discharge tube was made by Eugene Ducretet (1844-1915) a leading French scientific instrument maker who opened his first shop retailing unusual scientific instruments in Paris in 1864. This instrument is engraved with his name E Ducretet A Paris to the top tap.
It is one of the largest, heaviest and most unconventional discharge tubes we have seen. Standing 60 cms high an in pretty good condition for its age – we have left the brass work as we found it – the threads to the vacuum inlet work albeit stiff and the thread to the to mount are in very good condition. The extremely thick glass tube is at a slight angle but the seals appear intact. A very rare scientific collectable from the early days of gas discharge experiments.
