Infrared heating and quartz tube radiating is employed, which strengthen the abilit of acid/alkali resistance, defend crack and increase the operating life, conforming to the CE standard.
Temperature and velocity are programmed and adjustable; temperature rises in a high speed and residuals are exterminated.
The heated area of the digestion tube is large and the temperature difference is samall, which guarantees the digestion consistency of the samples.
Over current and electric leakage protection are applied.
Double switches and respective ontrol of the power supply and heating unit are convenient for te setting of safety parameters and energy saving.
A temperature controller with new digital display and PID control technology ensures the high accuracy of temperatue control.
Stainless steel equipment is used for the sewage disposal, which drains the harmful gases such as SO2 produced in the digestive process through the drainage pipe y suction pump, effectively inhiiting the escape of the harmful gases.
An anti-explosion device for samples.(optional)
Heating theory of Quartz
The far infrared quartz heating element made of pearlized milky white quartz tube and electric thermal material entitles it good and relaible far infrared radiated characteristic. After electrifying, the infrared light released by the thermal materials and 97% of the visible light are assimilaed by the white quartz tube, leading to the temperature elevation of the tube wall and the vibration of silicon-oxygen molecule, which radiates the far infrared light 97% visible light and near infrared light are transformed into infrared radiation. It overcomes the defect of bringing visible and near infrare lights through the transparent quartz glass, and effectively transforms the electric power into far infrared light.
