Gerhardt has been offering fully automatic systems under the brand name Soxtherm. The solid-liquid extraction according to Soxhlet and Twisselmann can be done much more efficiently by using these systems. Thus, the Soxtherm simplifies and accelerates the traditional Soxhlet method in key areas. The extraction has up to five programmable stages. The patented process is fully automatic and is especially useful for the determination of fat and for residue analysis.

Depending on the size of the laboratory and the sample throughput, the customer now has the option of a 2, 4, or 6 place system. The controller, Multistat, can control and monitor up to 4 units individually.
