Abstract

<PICT:0387795/III/1> A device for carrying out chemical tests particularly those involving the distillation and absorption of a volatile substance consists of a flat dish 1 provided with a gastight cover 6 and divided by a partition 3 into two compartments containing respectively the substance to be tested and the absorbent. The partition is so designed that the volatile constituent can pass from one compartment to the other. The device is preferably circular with a concentric circular partition. The use of the apparatus for the estimation of small quantities of ammonia is described in detail.
