Application Area：
HW series graphite digestion system adopt international advanced technique, realize integration of design, has the advantage of quick digestion, high efficiency, energy-saving, convenient. It has been successfully used for Sample preliminary treatment of Environmental Protection, chemical, food, Medicine and biochemical industry, it is also apply to pr-treatment, evaporation and cooling treatment for microwave digestion. Provide ideal auxiliary product for analytic equipment such as atomic absorption, atomic fluorescence, ICP-AES, etc.
Functions and features:
ïµEven heating: Heating material use high-temperature endurable graphite with excellent thermal conductivity, guarantee the uniform temperature among individual digestion holes. Temperature difference between samples is less than ±2.0 ℃. When digest multiple samples simultaneously, it ensures that each sample is under the same reaction temperature and conditions. This makes it possible for batch processing and overcomes various kinds of defects of traditional plate-type platen heater.
ïµAnti-corrosion：Graphite surface is covered with Teflon Coating, make clean convenient and provide good resistance to corrosion. The equipment can be used in the strong acid or alkali environment with 100% ease.
ïµPrecision control: PID temperature control system, simple and convenient operation, high performance, durable in use, high temperature control precision (reach ±1.0℃), adjustable heating rate, temperature increase and temperature maintain time are controlled by program, when program finish, heating process is stopped automatically.
ïµHigh efficiency: The maximum temperature reaches 460℃. 54 samples can be treated simultaneously, greatly improve efficiency.
ïµWidespread use: used for laboratory normal heating reaction, precisely sample digestion control, quick sample evaporation and cooling after microwave digestion, make up to volume directly without shift.
