Using advanced PID temperature control technology, it takes only 20 minutes to heat to 400℃ with high accuracy.  There are two modes of temperature control: curve heating and linear temperature heating. It can edit and store 10 groups of digestion programs. Each group can set up a segment temperature and time gradient of up to 5 to meet different experimental needs of users.


  1. 20 positions, enhance working efficiency rapidly.
  2. Corrosion-resistant design.
  3. It adoptsadvanced insulation technology, which is eco-friendly, and can minimize  energy intensity.
  4. Multi-protection, over-current protection, high temperature warning, overload protection.
  5. LCD display.
  6. It’s used with microwave reaction system, so as to pretreat for microwave digestion or removing acid after digestion.
  7. Linear and curve temperature rise mode, up to 5 stages temperature setting.
  8. Curve temperature rise and linear temperature risetemperature control modes.

Gas Collection Hood—KJD-WGH:

  1. Using PFA sealed cap, longer life, excellent dealing effect.
  2. Clip-on sealing cap, easy for changing.
  3. Specialized water jet vacuum pump is adopted, noneed for electric power.
  4. Drip tray design, beneficialfor reducing corrosion damage from acid solutions.
