Laboratory installation for treating a sample in a reactor R1 to R8 by successive macerations with several liquids coming from treatment liquid sources 12 to 15, characterised in that the reactor R1 to R8 forms, with connecting pipes 3 to 11 connecting it to the treatment liquid sources, a water-tight assembly in which these pipes are fitted with solenoid valves V1 to V8 and V12 to V15 while a priority scheduling unit 22 is electrically connected to these solenoid valves as well as to a drainage control means 19 in order to set up a sequence of operation according to a modifiable programme. <IMAGE>
