Gr20 Automated Graphite-Block Digestor

This kind of graphite digestor is adopted with the economic high purity graphite heating method and the anti-oxidation processing. Comparing to that of the aluminum block, the price of the graphite digester is more acceptable to most of the laboratories.

Product Introduction:

This kind of graphite automated digestor is adopted with the economic high purity graphite heating method and the anti-oxidation processing. Comparing to that of the aluminum module, the price of the graphite automatic digestor is more acceptable to most of the laboratories.


Application Scope

This graphite digester is widely applied in the industries of food, pharmaceutical, agriculture, forestry, environment protection, chemical engineering, biochemistry and etc. For those colleges and universities, and other scientific research departments, which will handle the sample digestion before chemical analysis of the soil, fodder, plant, seed, mine and etc, it is better to equip Sonnen’s Kjeldahl apparatus together with this graphite digester.  


Product Feature:

  • Heat insulation methods: Ceramic insulation and air duct insulation;

  • Heating method: Infrared radiation and graphite conduction heating;

  • Temperature is adjustable and constant;

  • Alarm of over voltage, over current, over heating, over temperature, and auto malfunction alarm;

  • Accurate PID outlet temperature control and safe over temperature protection are specially designed;

  • The outer surface is painted with teflon coating to prevent the apparatus from being corroded by the acid gas or liquid generated during the digestion;

  • The exhaust manifolds should be connected to the water aspirator supplied, or to a suitable scrubber


Optional Spare Parts:

Sonnen’s E Series Off-gas Absorption Apparatus: connection of the digestor and off-gas absorption system, to neutralize and absorb the acid fume generated during digestion.
