An automatic acid hydrolysis system for fat determination according to Weibull-Stoldt where the complete digestion and filtration process runs in a closed system.

• Time saving, reproducible operation
• The apparatus can be operated outside a fume cupboard
• Laboratory personnel have no contact with hot acids and acid fumes
• Sensors control temperature, cooling water, fill level of the tanks, dosing and addition automatically
• Each module can be individually and independently controlled using the supplied HYDROTHERM Manager software
• Data logging: The control program logs and documents the individual work operations and apparatus values for each hydrolysis process

Six samples can be digested simultaneously using three independently controllable modules, each with two hydrolysis units. HYDROTHERM meters the hydrochloric acid into the sample beaker, hydrolyses the sample in boiling hydrochloric acid and performs the complex filtration with all rinse operations completely automatically. The user can control the temperature, time and rinse parameters to ensure all fats content is transferred and the filter has been washed to pH-neutral. Sensors permanently monitor the process and abort it in the event of faults.
