Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of can guarantee internal temperature field magnetic stirring apparatus more uniformly.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of magnetic stirring apparatus; Comprise magnetic stirring apparatus, stir cover and be used to measure the temperature measuring mechanism that stirs cover internal-response liquid, said stirring is covered with stirs the cover cavity volume, and stirring the cover cavity volume is column structure.
Through adopting technique scheme; Changed the shape that stirs cover, column structure is more even than traditional bowl shape temperature field, stirs in the cover cavity volume if agitated reactor is placed on; Fluid temperature in the agitated reactor is even, so just can reach the purpose that stirs with effective temperature control.
The utility model further is set to: described column structure is a cylindrical-shaped structure.
Through adopting technique scheme, the agitated reactor major part on the market is a bowl structure, stirs the cylindrical-shaped structure setting of cover cavity volume, makes that temperature field on every side is more even after agitated reactor is put into stirring cover cavity volume.
The utility model further is set to: said stirring cover is connected with and stirs the cover seal cover.
Through adopting technique scheme, make that further stirring cover cavity volume temperature inside field is more even.
The utility model further is set to: be provided with magnet between said magnetic stirring apparatus and the stirring cover.
Through adopting technique scheme, make magnetic force stronger, stirring action is obvious.
The utility model further is set to: said temperature measuring mechanism comprises tempilstick, temperature indicator and temperature controller, stirs to be covered with the through hole suitable with tempilstick, and tempilstick is placed in the through hole and is placed on and stirs in the cover cavity volume.
Through adopting technique scheme, can be so that stir the state that cover is in sealing fully, need not to expose little opening and remove to let the tempilstick thermometric at the opening part that stirs cover, make that the temperature of measuring is more accurate.
The utility model further is set to: be provided with agitated reactor in the said stirring cover cavity volume, be provided with the ware that holds that is used to hold reaction liquid in the agitated reactor, hold ware and be made by polytetrafluoroethylmaterial material, be provided with magnetic agitation said holding in the ware.
Through adopting technique scheme; Because polytetrafluoroethylene (PTFE) has the characteristics of antiacid alkali resistant, anti-various organic solvents; Be dissolved in the characteristics of all solvents hardly; Liquid put into to be made into by polytetrafluoroethylene (PTFE) hold the ware internal ratio directly liquid to be put into the agitated reactor that is made of metal reasonable, avoided the damage of agitated reactor.
