Product Introduction:

This kind of graphite automatic digester 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 automatic digestor is more acceptable to most of the laboratories.


Application Scope:

  • The digestion of the samples of nitrogen and protein;

  • COD digestion;

  • The digestion of total phosphorus, arsenic and etc;

  • The digestion of heavy metal (such as lead, copper, zinc, tin and etc.)


Product Feature:

  • Large LCD screen is equipped for display, and the touch-button is anticorrosive.

  • Intellectual temperature control, time control, and curve heating function (double-mode、three-stage heating) ensure that this digester is suitable for a wide range of digestion samples;

  • Large screen, with switching display function, displays the working condition (real-time temperature and remaining heating time) in real time and makes it convenient for observation; 

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

  • Alarm function of over voltage, over current, overheating, over temperature, and auto malfunction alarm function are available;

  • Intellectual failure detection (for the heating unit, temperature control unit, temperature sensor and etc.) is available and the detection result will be output in English words;

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

  • 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;

  • Heating method: Infrared radiation and graphite conduction heating;

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