Heating stirrer for low viscous reagents

Abstract

The invention discloses a heating stirrer for low viscous reagents. The heating stirrer comprises a supporting seat and a mounting seat. A motor is arranged in the mounting seat, an opening is arranged at the upper end surface of the mounting seat, and a rotating plate is arranged on an extension segment of the output end of the motor. A plurality of magnetic strips are arranged on the upper end surface of the rotating plate, a through hole is arranged in the upper end surface of the supporting base, a heat conducting plate is arranged on the upper end of the through hole, and a non-magnetic heat insulation board is arranged on the lower end of the through hole. A plurality of heating pipes are arranged in the heat conducting plate which is arranged on the through hole, a base is arrangedon the inner wall of the bottom of a cup body, magnetic blocks corresponding to the magnetic strips are installed on the base, and a plurality of stirring blades are fixed on the upper surface of thebase. By accessing a power supply at an electric socket, the heating pipes start to generate heat, and the heat is transferred to the cup body by utilizing the high thermal conductivity of the heat conducting plate, and since the non-magnetic heat insulation plate is disposed at the lower end of the through hole, the heat generated by the heating pipes is prevented from being transferred downwardsto the mounting seat and further to prevent normal operation of the motor from being disturbed.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a heating and stirring device for low-viscosity reagents. Background technique [0002] In many chemical experiments, in order to detect the concentration or ratio of certain trace elements, it is necessary to rely on the color change during the reaction, and then make a judgment by visual observation. Such as "liquid CaCl2" content detection. In order to speed up the process of the test, magnetic stirring is usually used to speed up the process of the sample reaction. At present, the magnetic stirrer available on the market generally controls the progress of the test by adjusting the frequency conversion, that is, placing the magnetic rod in the container and changing the rotation speed of the magnetic rod in the container, but the above method is only suitable for small It is difficult to test the test of large-capacity liquid. When the magnetic stirrer stirs the liquid with large ca...

At present, the magnetic stirrer available on the market generally controls the progress of the test by adjusting the frequency conversion, that is, placing the magnetic rod in the container and changing the rotation speed of the magnetic rod in the container, but the above method is only suitable for small It is difficult to test the test of large-capacity liquid. When the magnetic stirrer stirs the liquid with large capacity, it is often difficult to fully mix the liquid inside the container. The experimental detection often causes the deviation of the experimental results or leads to a longer test cycle
