Widely used in environmental protection, scientific research, as well as industries such as petrochemicals, metallurgy, and printing and dyeing. Used for pre-treatment equipment of hexavalent chromium in soil.
Applicable standards:HJ 1082-2019
Soil and Sediments Determination of Hexavalent Chromium Alkali solution extraction-Flame Atomic Absorption Spectroscopy
Instrument features:
1. The heating material is all aluminum, with surface oxidation treatment. The heating method is single hole single cup heating, and the temperature difference between the heating holes is ± 1 ℃. Compared with the old-fashioned magnetic stirrer, the temperature difference is small and the error is low.
2. This magnetic heating stirrer does not require a temperature sensor to be placed, avoiding interference with the sample caused by placing the sensor in the beaker in the old magnetic stirrer.
