Abstract

Appts. for automatically ensuring that the quantity of liq. removed by a diluter does not vary in successive operations, in which an air bubble, present in the sampling tube and situated between the liq. being sampled and the diluent or reactant, is automatically detected by means of a suitable pick-up, which verifies the position in the tube of one of the ends of the column of liq. being sampled, the other end being necessarily at the level of the sampling inlet.
