A simple set to produce selected gases

MACHINE TRANSLATION (not authorised yet)

Combination for the production of selected gases. The set includes a water container with lid, 5 glass tubes (150x24 mm) with plugs, 1 glass tube with tube (side arm) and plug with a drilled hole, tube stand, 2 tubes, bent glass tube approx. 40 cm long, flat-bottomed glass flask with bottom tube.
Gases (e.g. oxygen, hydrogen, carbon dioxide) produced by the elements of this educational set accumulate above water and lie in the flask (if the gas produced is heavier than air) or in the superimposed tubes (if the gas is lighter than air).
An instruction manual with the course of the sample experiment is included in the set.
