Abstract
The utility model relates to a drainage tube in the drainage process of chemical experiment, consisting of a glass rod 1 and the v-shaped groove2. The angle of the V-shaped groove is smaller than the V-shaped port of the beaker. The utility model is the experimental instrument improved by the glass rod and can reduce the error in the experiment process of the drainage, stirring with the glass rod and provides the convenience for the experimenter in the operation process.
Description
Technical field
The utility model relates to the drainage tube that uses in the chemical experiment drainage process operation.
Background technology
Glass bar is in the operating process of drainage, because glass bar is circular, drainage liquid can flow through the gross area of glass bar, causes experimental implementation error to occur; During drainage procedure, the instrument of splendid attire drainage liquid is point and contacting of putting with circular glass rod, so just is easy to slide, and will cause drainage liquid directly to be poured in the purpose container thus, and glass bar does not play the effect of drainage in this process; Circular glass rod is easy to rolling take place and smash in the simple and crude laboratory of rack for test tube not having; When holding glass bar and operating, when hand contacted with circular rod, the application point of power was on circular face, caused the active force between them little, and glass bar easily slides in hand.Though glass bar is simple in structure, volume is little, is bringing into play very important effect in the experimental implementation process, but it also exists the shortcoming of can not ignore when playing a role.
Summary of the invention
The purpose of this utility model is to provide drainage tube, and it is a kind of by the improved laboratory apparatus of glass bar, can reduce glass bar caused error in experimental implementation processes such as drainage, stirring effectively, and brings convenience for the experimenter in the process of manipulating.
The utility model purpose is achieved in that opens " V " type groove in the length range of glass bar, the angle of sulculus is littler than " V " type bicker degree of beaker, drainage liquid promptly can flow down along drainage tube " V " type sulculus, and can not spread to other places of drainage tube, the instrument of splendid attire drainage liquid and drainage tube are to contact with 2 form.Therefore, two instruments are very firm when contact; The drainage tube that when holding drainage tube, has " V " type groove can not slide in hand; The raw material of making drainage tube has also been saved in the use of " V " type groove.
Drainage tube is characterized in that, mainly is made up of glass bar and " V " type groove of offering thereon.The angle of described " V " type groove is littler than " V " type bicker degree of beaker.
Compared with prior art, the utility model is because only need open " V " type groove on glass bar, so structure is simple especially, the existence of " V " groove has changed original circle, therefore glass bar place or hand take all very convenient, to drainage tube mode of operation, clear problem without any special requirement; And the speed of toppling over of drainage liquid also is easy to control when drainage.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2.
Drainage tube is characterized in that, mainly is made up of glass bar 1 and " V " type groove 2 on it.The angle of described " V " type groove is littler than " V " type bicker degree of beaker.
When carrying out drainage procedure, drainage liquid flows down along " V " type groove 2 on the drainage tube glass bar 1, is stirring etc. when holding the operation of drainage tube, and firm active position can not rotate drainage tube in hand, when being placed on the horizontal plane, can not slide.
Claims (1)
1 drainage tube is characterized in that, mainly is made up of glass bar (1) and " V " type groove (2) on it, and the angle of described " V " type groove is littler than " V " type bicker degree of beaker.
