Application method of the present utility model：Chemical reaction rate experiment instrument of the present utility model is in use, first by Boiling tube
It is inserted perpendicularly into the Boiling tube hole of lower cross frame, small test tube is inserted perpendicularly into the lab scale pore of upper crossbearer, transposed by lower cross frame
The front and back position in handle regulation Boiling tube hole, when making the rotation of lab scale pore, the reaction liquid energy in lab scale pore pours into big examination just
In pipe, then, reaction solution is separately added into Boiling tube, and crossbearer in another reaction solution, rotation is separately added into small test tube and is revolved
Handle is changed hands just by the reaction solution in small test tube while pouring into Boiling tube, experimenter chemically reacts to contrast plate as background observation
The phenomenon of rate experiments.Standby test tube, which can stand upside down, to be placed on storage rack for test tube.
The beneficial effects of the utility model, chemical reaction rate experiment instrument of the present utility model, its is rational in infrastructure, ingenious,
Experimenter successfully realizes while addition reaction solution, reduces operation sequence, avoids the time difference for adding reaction solution, make chemistry
Reaction is carried out simultaneously, improves the accuracy of chemical reaction rate experiment, while effectively prevent the spilling for adding reaction solution, is carried
The high security of chemical reaction rate experiment.With promotional value.
