vacuumAcid removerProduct Introduction:

GS-12Vacuum acid removal systemAdopting technologies such as graphite heater, constant temperature controller, vacuum pump, and collection bottle. The graphite heater generates high-temperature heating of the sample, which vaporizes the acid in the sample into acid vapor and pumps it into an alkali solution collection bottle through a vacuum pump until the acid gas reaches the allowable amount in the laboratory, avoiding damage to the precision detection instrument caused by high concentration acid. The vacuum system accelerates the formation and transfer of steam, thereby saving acid rush time. As each sample is completed in an independent space, it improves the accuracy and repeatability of instrument analysis.

Main features of GS-12

Vacuum pump absorption device：

1. It can be matched with any brand of digestion equipment on the market, such as Antonpa, Milestone, Shanghai Xinyi, Yiyao, etc.

2. The entire system is a closed system, provided with vacuum by a vacuum diaphragm pump, and operates under negative pressure. All acid vapors are absorbed by the alkaline solution to prevent pollution;

3. Shorten the 3-4 hours required for atmospheric acid removal to 30-40 minutes (150 degrees), greatly improving the efficiency of acid removal;

4. Flexible handling of sample quantity, not limited by sample quantity, can process 1-20 samples simultaneously. When checking the acid rush situation of a certain sample, there is no need to stop the acid rush work, which does not interfere with the acid rush of other sample tubes;

5. Real time monitoring of the acidity level of each sample to avoid evaporation;

6. For volatile elements, the acid recovery temperature can be reduced to provide element recovery rate;

7. The entire vacuum device is made of imported PTFE material, greatly extending its service life.

Characteristics of GS-12 graphite digester:

1. Elegant appearance: neat and tidy, with various buttons arranged reasonably and neatly.

2. Clean and corrosion-resistant: The heating body of the heater is coated with a thick PTFE coating, which is corrosion-resistant and resistant to pollution. Adopting a unique spraying process, the coating is uniform, firm, and will not peel off even after long-term use. The heating element and tabletop are made of high-quality graphite with thermal conductivity, high temperature resistance, and corrosion resistance. The controller body adopts anti-corrosion coating, which can be used with confidence in corrosive environments such as strong acids and alkalis.

3. Efficient: Adopting advanced integrated surrounding heating method, 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 thorough digestion.

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 significant heat loss, leading to a large gap between the sample temperature and the surface temperature of the heater.

4. More economical: 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.

5. 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

6. Superior thermal conductivity: A reasonable heating method paired with a heating element with superior thermal conductivity can ensure temperature uniformity between each digestion well, with a temperature difference between samples of less than ± 1.5 ℃ (room temperature -240 ℃). When digesting multiple samples, it can ensure the same reaction temperature and conditions for batch processing.

Main application areas of GS-12
