Gerhardt Kjeldatherm Block Digestion Units

The compact Kjeldatherm block digestion systems allow for simultaneous multiple digestions. A precise temperature control permits the conditions for the digestions to be optimized thus providing reproducible results.The comprehensive product range of Kjeldahl models made by Gerhardt includes digestion systems for Kjeldahl digestions in 100 ml, 250 ml, and 400 ml tubes. An excess temperature protection as well as an excess current switch are now part of the standard equipment. The temperature control is provided by an external controller, which is included in the standard configuration

 

 

 

 

Kjeldalift

In the digestion systems with the Kjeldalift the two tier console is equipped with a lift for moving the insert rack plus manifold in and out of the block. All functions are controlled by the TZ-controller

The construction

All digestion blocks consist of the following components:

  • Kjeldatherm digestion block made of aluminum with holes for digestion tubes.
  • Energy efficient heating and insulation to retain heat within the block and to protect the user.
  • Insert rack made of aluminum with two side positioned insulated handles.
  • Integrated heat shield and window provide easy and safe observation of the samples.
  • Exhaust system with heat insulated handles, integrated glass exhaust manifold and water jet pump.
  • Exhaust system and digestion tubes can be easily and safely handled separately.
  • Two-tier console mounted directly on the block. The insert rack as well as the exhaust manifold can be stored safely above the block during the cooling down periods. This has a positive impact on the safe operation of the Kjeldatherm and at the same time, saves horizontal bench space.
  • Kjeldatherm digestion tubes depending on the system used KMT (100ml), KTG (250 ml) or BS (400 ml).
  • External controller


Kjeldatherm-automatic

When using the automatic digestion systems the handling of the insert rack and manifold is done with the help of the lift-motor. For the fully automatic programming we recommend the temperature-time-controller TZ. The controller is included in the standard configuration

Kjeldatherm-Basic

When using the manual digestion systems the handling of the insert rack and manifold are done manually.
For all manual digestion systems we include the controller TR. For a fully automatic system we recommend the temperature-time-controller TZ. The controller is not included in the standard configuration.
