Embodiment 1
[0025] according to figure 1 As shown, the specific working mode of the laboratory vessel cleaning device of the embodiment of the present invention is as follows:
[0026] Press the push-type stepless variable speed regulating switch, and the metal-free acid and alkali resistant water pump will start accordingly. The water pump draws the pure water in the barrel and flows into the outlet head with the thin hose. The rotational power of the water pump is determined by the input voltage, and the input voltage is determined by the pressing force of the stepless speed control switch.
[0027] The purpose of this embodiment is to dilute a large number of 25ml colorimetric tubes to 25ml with pure water. In order to achieve this purpose, firstly insert the spout water head into the hard pipe, and fill the bucket with pure water. Then vigorously press the stepless variable speed control switch, the water outlet head of the sharp mouth will quickly discharge water, when the pure wa...
Embodiment 2
[0030] The purpose of this embodiment is to complete the step of adding mixed acid in the digestion process.
[0031] The conventional digestion steps are: put the powdered sample into a polytetrafluoroethylene crucible, first add a small amount of water to wet it with an ordinary washing bottle, then add a certain amount of mixed acid with a pipette and other tools, and finally heat it for digestion. In the step of adding the mixed acid, if the mixed acid is added directly, when the acid is added too fast, the acid will splash when it hits the bottom of the crucible, and cause a small amount of sample to be lost with the splash. In order to avoid this situation, usually use a common wash bottle to add a small amount of pure water to wet the sample, and then mix the acid to prevent acid splashing. When using an ordinary washing bottle to add pure water to the crucible to wet the sample, since the arm is in a suspended state when holding the washing bottle, the arm will be sore...
