1. Power supply: A.C 220V±10% 50Hz, input power: 1600W

2. Temperature setting range: room temperature ~ 450℃

3. Temperature control accuracy: ±0.1℃

4. Temperature difference between holes: less than ±1.0℃

5. Heating hole and size: 30 bits * 30mm (hole diameter) * 55mm (hole depth)

60 bits * 40mm (hole diameter) * 55mm (hole depth)

6. Control system: split control, LCD digital display

7. Temperature control method: PID temperature control system.

1. Isostatic high-purity graphite is used for uniform heating and corrosion resistance;

2. High efficiency: the advanced integrated surround heating method is used, and all parts of the sample are heated evenly, which prevents heat loss to the greatest extent, eliminates the temperature difference between different parts of the same sample, and digests quickly and thoroughly;

3. The PID temperature control method is used, with high temperature control accuracy of ±0.2℃, adjustable heating rate, controllable heating holding time, stable heating rate, high and low temperature alarm, and automatic heating stop;

4. Excellent thermal conductivity: The reasonable heating method is matched with a heating body with excellent thermal conductivity, which can ensure the temperature uniformity between each digestion hole, and the temperature difference between samples is less than ±1.5℃ (normal temperature ~ 250℃). When digesting multiple samples at the same time, the same reaction temperature and conditions can be guaranteed for each sample for batch processing.

It adopts international advanced technology and has the advantages of fast digestion, high efficiency, energy saving and convenience. It has been successfully used in sample pretreatment in environmental protection, chemical, food, medicine, biochemistry and other industries. It can also be used for pretreatment and acid removal of microwave digestion. It is an ideal supporting product for atomic absorption, atomic fluorescence, ICP-AES and other analytical instruments.
