Abstract
The utility model relates to the technical field of experimental instruments, and provides a weighing spoon and a weighing system.The weighing spoon comprises a spoon handle, a spoon head, a driving part, a cover plate and a control key; the spoon head is provided with an opening. The spoon head and the driving piece are both connected to the spoon handle. The edge of the cover plate is connected with the driving piece. The driving piece is used for driving the cover plate to be connected with or separated from the side, provided with the opening, of the spoon head in a switchable mode. The control key is electrically connected with the driving piece and used for controlling the driving piece to be turned on or turned off. Therefore, when an experimenter holds the spoon handle to transfer the chemical reagent, the scattering amount of the chemical reagent can be reduced, the waste of the chemical reagent can be reduced, and the experiment cost can be reduced. In addition, the efficiency of scooping up the chemical reagent can be improved, the cover plate is prevented from being polluted by external objects in the moving process, and therefore the scooped chemical reagent can be prevented from being polluted.
