Overview
The HZLB KDN-08C digester is a laboratory equipment for sample digestion, which can process 8 samples at the same time. The whole machine adopts special spray steel plate and stainless steel table surface, which has good corrosion resistance. The instrument adopts digital display and digital display control, Temperature range is wide, heating speed is fast, and multiple Safety protection.
Features
1. Using quartz infrared heating tube, radiation heating is the main one, conduction is the auxiliary one, the heating speed is fast and the efficiency is high.
2. The temperature controller directly displays the set temperature and the actual temperature, and automatically stops heating after reaching the set temperature.
3. The chassis of the whole machine adopts special spray steel plate, the working surface is made of stainless steel, which is resistant to corrosion; the exhaust gas sealing is made of polytetrafluoroethylene material, which is safe and reliable.
4. Double-decked shell design, including air insulation layer and aluminum silicate insulation layer, double insulation effect is good.
5. With multiple protections such as overvoltage, overcurrent, and overheating, it is safe and reliable.
6. The whole machine is small and beautiful, easy to operate, and easy to use.
Principle
The instrument generates heat through a quartz infrared heating tube, and uses radiation as the main method to heat and digest the sample. The temperature control system monitors and displays the actual temperature in real time, and automatically stops heating when the preset temperature is reached to achieve accurate temperature control. The digestion process is carried out in a sealed digestion tube, and the exhaust gas is sealed with polytetrafluoroethylene material.
Applications
Laboratory sample digestion, nitrogen content determination
Steps
1. Place the sample to be digested into the digestive tube.
2. Set the required digestion temperature.
3. Start the instrument to start heating and digestion.
4. The instrument automatically stops heating after reaching the set temperature, and the digestion process usually takes 60-90 minutes (the specific time depends on the sample volume).
5. After digestion is completed, the sample is removed for subsequent analysis.
Notice
* Power supply voltage is 220V 50Hz before use.
The digestion time should be adjusted according to the sample volume.
Please pay attention to the high temperature part of the instrument during operation to avoid burns.
* Please ensure that the exhaust gas sealing device is intact to prevent leakage.
When the instrument is working, do not cover or block the heat dissipation holes.
* Regularly check the status of the instrument to ensure that the Safety protection function is normal.
