For many years, Gerhardt has been a successful manufacturer of an automated rapid Soxhlet system: Soxtherm. Thanks to the close relationship with our customers and partners worldwide, this highly successful instrument has been improved further.
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. The savings in costs and space are tremendous. The fully automated process ensures highest precision for minimum input.
Concept
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.
Convincing arguments
- 3 units available plus micro/macro choice giving the widest range of options for all laboratories
- Solvent recovery reduces running costs
- Water and compressed air control give unattended operation and saves water making the system environmentally friendly
- Fast and accurate giving an increased sample throughput compared to the traditional Soxhlet
- Capable of being used with all solvents giving flexibility of applications
- Fully programmable with automatic start-up and shut down for unattended operation
- Low solvent usage reduces running costs
- Only 3 moving parts and no internal seals means no routine maintenance is required
- Large thimbles available for large sample sizes
- Single button operation for ease of use
- One Multistat controls up to 4 units which gives lower cost upgrades
Safety features - Cooling water and air monitoring
- Safety door protects the operator from hot surfaces
- Over temperature cut-out prevents flash point of the solvent being exceeded
- Optical sensor on solvent recovery tank prevents over filling
- Acoustic and visual warnings inform operator of system problems
- Spark proof heaters to DIN/VDE 0170 and 0171 meet the high standards required
- Illuminated glass beakers allow easy visual inspection of extraction progress
