Semi-Automatic Digesters

The DK 20 Series digestion unit with aluminum heating block ensures high thermal homogeneity heating up to 450 °C. The temperature of the block is constantly controlled by a microprocessor and is extremely stable, homogeneous and precise: ±0.5°C at all selectable temperatures.

The design of the DK series has been carefully engineered to allow laboratories to save valuable space under the hood. DK Digesters have very compact dimensions: the new aluminum heating block has been lowered and the vertical proportions allow to free precious space in the laboratory.

The bright digital display provides maximum visibility and easy-to-read information. The instrument is operated with 4 keys to navigate the menu options and program the digestions in a simple and fast way. Through the intuitive graphic display it is possible to set up to 20 methods with 4 temperature ramps. Acoustic signals inform the operator of the completion of the analysis facilitating the daily use of the digester.
