The simplest handling

The locking system allows the reactor to be opened and closed quickly and safely in just a few steps.

Digestion of any type of sample possible

Digestion times of up to 72 h at 250°C are possible. This allows digestion of even the most challenging samples.

Excellent operating and handling safety

This is ensured by rupture discs as well as design, production and testing in accordance with AD-2000 and Pressure Equipment Directive 2014/68/EU.


Product Description

The most difficult sample materials or sample quantities up to 5 g can be digested with the digestec pressure digestion system. Digestion times of up to 72 h at 250°C are possible, making it the ideal digestion system for customers who have challenging samples or constantly need to digest new materials.

A new field of application is screening approaches in hydrothermal or solvothermal synthesis.

Ease of use

Easy handling based on intelligent closing system.

The easy-to-use closing system enables fast opening and closing of the reactors. Only one screw has to be tightened with a torque wrench to fully close and seal the system.


The unique TFMTM-PTFE lining offers most extensive protection against corrosive media - even in the gas phase.

During operation at 200 bar and up to 250 °C the several millimeter thick TFMTM-PTFE lining of reactor vessel and lid is braced by a stable stainless steel coat. Before and after operation the TFMTM-PTFE vessel is removed easily from the steel coat and serves as a container for the probe. Also, the use of several TFMTM-PTFE vessels allows very high sample throughput.

Screening experiments

Ideal for parallel screening experiments.

Heating blocks with several positions enable screening experiments of up to 48 probes parallel managed by only one controller. Hence, the DAB-system offers highest sample throughput of all Berghof reactors.


Easy handling and maximum user safety

  • Bayonet lock for easy and fast opening and closing
  • Overpressure protection by means of rupture disc
  • Controlled pressure release when opening
  • Designed and manufactured according to AD 2000 and Pressure Equipment Directive 2014/68/EU
