Graphite digestion instrument

1、 Usage Overview:
In most metal element analysis processes, the wet sample digestion method is recommended as a sample pretreatment method by inspection agencies and standards due to its advantages of easy operation and low equipment cost. However, the current wet digestion methods mostly use flat plate or water bath electric heating devices, which all have problems such as uneven heating, inaccurate temperature control, low thermal efficiency, and require a large amount of electricity to process a batch of samples. Relatively speaking, the wet digestion device made of graphite material that is lightweight, inert, has fast and uniform heating and thermal conductivity can effectively solve these problems, and is accepted by many inspection institutions for its moderate price, energy saving and environmental protection. It has now become one of the commonly used equipment in laboratories.
Our company uses high-quality high-purity graphite materials and has independently developed an intelligent graphite digestion instrument. This graphite digestion instrument adopts technology and has the advantages of fast, efficient, and convenient digestion. It is suitable for sample digestion treatment before chemical analysis of soil, food and feed, plants, seeds, ores, etc. in industries such as agriculture, forestry, environmental protection, chemical engineering, food, medicine, biochemistry, as well as higher education institutions and research departments.

2、 Functional features:
1. The temperature inside the furnace is continuously adjustable, the controllable temperature is constant, and the instrument operation is simple
2. The average temperature difference inside the furnace is small, the sample digestion effect is good, and the heat conduction efficiency is high
3. The whole machine chassis is made of stainless steel material, which has good corrosion resistance
4. Adopting anti-corrosion components, it can be used with confidence in corrosive environments such as strong acids and alkalis
5. The whole machine has multiple protections such as overvoltage, overcurrent, and overheating
6. The heating of each part of the sample is uniform, which greatly prevents the loss of heat
7. A high-performance heating element that ensures temperature uniformity between each digestion well
