S20 Automated Graphite-Block digester
Keywords: analytical instruments
Category:
details
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；
