Abstract

The invention discloses an acid removal device. The acid removal device solves the problem that a solution in a digestion tube is evaporated or coked because of the negligence of an experimenter so that the experiment is failed. The acid removal device comprises multiple digestion tubes, a heater comprising a heating flat plate of which the upper surface is provided with multiple vertical heatingholes, a digestion tube support frame provided with digestion tube vertical guide sleeves corresponding to the multiple vertical heating holes, wherein the digestion tube vertical guide sleeves are located above the corresponding vertical heating holes, and multiple self-adaptive heating isolation devices which are corresponding to the vertical heating holes, wherein the self-adaptive heating isolation device comprises a guide slide block sliding in the vertical heating hole, a reset compression spring between the bottom surface of the vertical heating hole and the guide slide block, a thermalinsulation support plate for supporting the digestion tubes above the guide slide block and a connection rod connecting the guide slide block and the thermal insulation support plate.

Description

technical field

[0001] The invention relates to an experimental equipment, in particular to an acid-removing device. Background technique

[0002] Acid removal is an important step in the detection of heavy metals in samples. Acid removal experiments usually need to drive the acidic solution in the digestion tube to 10-20% of the original volume. The acid removal process usually takes 3-4 hours, which takes a long time, and there are often differences in the acid removal time between multiple digestion tubes , so it is necessary for the experimenters to pay attention to the acid removal process at all times, so as to avoid the solution in the digestion tube from being evaporated to dryness; fail.

[0003] On the other hand, the acid vapor volatilized during the acid removal process will also permeate the laboratory, which will not only pollute the laboratory environment, but also damage the experimental equipment and cause physical injury to the experimenters. Contents o...
