Beschreibung
Zusammenfassung:	The test apparatus is equipped with two valves, of which the valve arranged in the test line 3 which branches off from the return line 1 is a seat valve 7 whose outlet aperture 13 forms the end of the test line, so that the amount of component emerging through the outlet aperture passes directly into the test beaker 6. The other valve, which is preferably a sliding valve 9, is designed and arranged so that one valve opens only when the other valve is closed, so that undefined flow through both lines 1 and 3 is avoided. The test apparatus permits error-free determination of the test amount per unit time. No residues remain in the apparatus, and the individual parameters which are important for the test result can be determined exactly and simply.
