This kind of graphite 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 digester is more acceptable to most of the laboratories.
Features
- 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..
- 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..
