Abstract: A device for splitting a sample, in particular a time-inhomogeneous sample, into two or more representative fractional samples, as well as a sample taking system with a sample splitter and a sample taker, wherein the sample splitter has a first pump (1, 201, 301) with a first flow rate and at least one second pump (2, 202, 302; 215) with a second flow rate, wherein the first pump and the at least one second pump (2, 202, 302; 215) co-act, so that the inhomogeneous sample on its passage through a conduit system (3, 203, 303) is at the same time split up into at least two representative fractional samples.

Abstract: A stirrer unit includes a reaction vessel having an inlet port, a shaft stirrer having a stirrer blade and a stirrer shaft connected to the stirrer blade, and an adapter defining a passage. The adapter is configured to be inserted into the inlet port and releasably fastened to the inlet port using a fastening device so that, in a connected state, the stirrer blade and a part of the stirrer shaft is disposed inside the reaction vessel. Furthermore, in the connected state, an immersion depth to which the stirrer shaft extends into the reaction vessel is adjustable and securable using a locking device in at least two positions that are spaced apart from one another.
