For determining the acid-soluble proportion of metals in sewage sludges, sediments and soils with aqua regia, e.g. in accordance with DIN 38414/German standard method.

Digestion in aluminium heating block with precise temperature control.
Racks and frame covered with special acid-resistant coating. Reliable technology from C. Gerhardt with innovative functions facilitate the daily routine in laboratories and enable a smooth digestion process.

Available with various configurations.

Reproducible digestion conditions

Programmable, precisely controlled temperature/time phases enable secure and reproducible digestion conditions. Up to 99 programs with max. 40 heating stages, 30 predefined methods and variable heating speeds ensure a high degree of flexibility. The programmable controller unit including data management supports the user with the compliance of the complex regulations of ISO 17025, GLP, etc.

Large number of samples in small area

Depending on the block system, 8 or 20 samples can digested simultaneously in 250 ml tubes. Thanks to the compact design, the limited space in laboratories can be used most effectively. The device has a footprint of only of 51.5 x 48.3 cm.

Convenient and safe

The pre-heat function of the digestion block saves valuable time and the user can start with the digestion program immediately. The motorised multi-level console enables convenient and safe lifting and lowering of the loaded insert rack.

The extraction unit and water jet pump provided or the powerful (optional) TURBOSOG fume suction station ensure effective extraction of acid fumes. TURBOSOG and the cooling water valve for optional water drainage can be switched on automatically.
