Description

Technical Field

[0001] The utility model relates to the technical field of chemical analysis, in particular to a vacuum acid remover. Background Art

[0002] In chemical analysis, in order to detect acidic solutions, the acidic solutions need to be treated, such as by acid removal. Acid removal involves removing the acidic solution in the digestion tube from its original volume to approximately 10% of its original volume. Existing acid removers manually remove the cover plate for manual sealing. However, this manual operation results in varying sealing effects, making it prone to leaks. Furthermore, existing acid removers heat the digestion tank to 150-180°C on an electric heater for 3-4 hours to evaporate excess acid. After the acid removal is complete, the digestion tank must be manually removed to shake the solution evenly, resulting in low efficiency. Utility Model Content
