Abstract

The invention discloses an automatic heating conical flask for chemical experiments. The automatic heating conical flask comprises a screw rod, telescopic rods and a bottom plate, wherein an electricheating wire switch is mounted at the bottom of the outer wall of one side of a main body through bolts; and a vibrating motor switch is mounted on the outer wall of the bottom of one side, away fromthe electric heating wire switch, of the main body. The screw rod is rotated by turning a handle so as to enable threaded sleeves to move on the screw rod; two threaded sleeves are provided, connecting rods welded to the lower surfaces of the threaded sleeves are connected with the telescopic rods, and the two threaded sleeves have different thread opening angles, so that when the two threaded sleeves move on the screw rod, the two threaded sleeves can draw close to the inner wall of the main body at the same time and also can move away from the inner wall of the main body at the same time; the distance between the two telescopic rods can be changed according to conical flasks with different volumes; through a vibrating motor, the conical flask placed on a vibrating table is vibrated, so that the effect of shaking in a vibrating manner while heating is achieved; the automatic heating conical flask provides convenience for the chemical experiments and is easy to be popularized and used.

Description

technical field [0001] The invention relates to the technical field of chemical experiments, in particular to an automatic heating Erlenmeyer flask for chemical experiments. Background technique [0002] An Erlenmeyer flask is a common glass instrument in a chemical laboratory. Erlenmeyer flasks are generally used in titration experiments. It is a titration reactor made of hard glass with a triangular longitudinal section. The small mouth and large bottom are conducive to the full reaction and the liquid is not easy to splash when the titration process is shaken. The container can be heated in a water bath or on an electric stove. The appearance is flat-bottomed and conical, with a wide bottom and a narrow top. It has a cylindrical neck and a wider opening above the neck. Sometimes it can be closed with a plug made of cork or rubber. There are several scales on the bottle to indicate the capacity it can hold. [0003] However, there are some disadvantages in the use of ...
