3、 Main features of SL-20A graphite digestion instrument

1. Elegant appearance: neat and tidy, with various buttons arranged reasonably and neatly.
2. The heating body of the room temperature digester adopts a thick PFA coating, which is corrosion-resistant and pollution-free. Adopting the spraying process of *, the coating is uniform, firm, and will not peel off during use. The heating element and tabletop of the high-temperature digestion instrument are made of high-quality graphite with thermal conductivity, high temperature resistance, and corrosion resistance. The control box adopts anti-corrosion switches, which can be used with confidence in corrosive environments such as strong acids and alkalis.
3. Adopting the integrated heating method of *, all parts of the sample are uniformly heated, which greatly prevents heat loss and eliminates temperature differences between different parts of the same sample, resulting in rapid and efficient digestion
4. Traditional electric heating sleeves, electric furnaces, etc. can only locally heat the sample container, resulting in uneven heating of the sample. There is a certain temperature difference between different parts of the sample, and the open heating method causes heat loss, leading to a significant difference between the sample temperature and the surface temperature of the heater.
5. Traditional thermal digestion samples usually take several hours, and difficult to digest samples can even take several days, consuming a lot of electricity; The surrounding heating process is fast, convenient, can save 75% of electricity, and has low operating costs.
6. Accurate temperature control: The PID temperature control system is easy to operate, has excellent performance, and is durable. High temperature control accuracy, up to ± 0.2 ℃, adjustable heating rate, program heating and controlled heating holding time, stable heating rate, high and low temperature alarm, automatic heating stop
7. Thermal conductivity: A reasonable heating method matched with a heating element with thermal conductivity can ensure temperature uniformity between each digestion well, with a temperature difference between samples of less than ± 1.5 ℃ (room temperature -210 ℃). When digesting multiple samples, it can ensure the same reaction temperature and conditions for batch processing.
