Abstract
The utility model provides a kind of graduated cylinder through improvement, primarily of two graduated cylinder, bottom drainage hopper with to be configured to.The utility model structure is simple, and capillary effect is cancelled out each other by the interaction that can be produced by the connection of two graduated cylinders, improves the accuracy of experimental data, reduces error, reaches desirable experiment effect.<b/>
Description
Technical field
The utility model relates to a kind of graduated cylinder, is specially one and can overcomes capillary effect through improvement, makes the more accurate graduated cylinder of measurement.
Background technology
Graduated cylinder is the main measuring device of one used in laboratory, mainly uses glass, and minority (particularly large-scale) uses transparent plastic manufacture, and its purposes by volume quantitatively measures liquid.Traditional graduated cylinder is perpendicular long open circles synform, on have sharp mouth along side, be convenient to topple over, there is wide pin bottom to keep stable, cylindrical wall is carved with volume range, reads volume for user.And when measuring liquid volume with graduated cylinder at ordinary times, all can be subject to capillary impact, make the volume of graduated cylinder measurement liquid inaccurate, produce deviation.
Utility model content
The purpose of this utility model is to avoid causing the inaccurate situation of data due to capillary effect when measuring and infiltrate liquid with graduated cylinder or do not infiltrate liquid volume.
For achieving the above object, this experiment is novel to be realized in the following ways: the right and left respectively has a graduated cylinder, connected by cored screw plug bottom two graduated cylinders, bottom centre has drainage hopper to be connected with funnel baffle plate, is furnished with bottom bracket, hold up stably in the left and right sides of two graduated cylinder, by the parallel pipe support of graduated cylinder both sides on the groove of support.
Graduated cylinder is perpendicular long cylindrical shape, is skewed bottom graduated cylinder.
The utility model utilizes the capillary effect of the force balance graduated cylinder on two graduated cylinder both sides, the force balance of capillary effect is offseted, more accurate when enabling graduated cylinder measure liquid volume, avoid the error of capillary effect liquid height that scale mark place causes in graduated cylinder.Tilt to central authorities bottom two graduated cylinder, be conducive to liquid in graduated cylinder like this toward intermediate flow, bottom centre is designed with drainage hopper, and bottom has support to support, can put a cup in funnel bottom, just the liquid flowing to center can be discharged, the liquid in graduated cylinder can be discharged by this design more easily sooner, make outside liquid outflow amount cylinder, be applicable to cleaning.
Accompanying drawing explanation
Fig. 1 is two graduated cylinder plane structure charts.
Fig. 2 is supporting structure schematic diagram.
In figure 1, graduated cylinder 3, cored screw plug 4, graduated cylinder coupling arrangement 5, bottom liquid outlet 6, groove 8, support 10, funnel baffle plate 11, drainage hopper.
Embodiment
Be described further the utility model below in conjunction with accompanying drawing example, the utility model is not only confined to this.
As shown in the figure, first the coupling arrangement 4 of spiral interface two cored screw plugs 3 are had to be linked together by two graduated cylinders by both sides the bottom of two graduated cylinders 1.Guarantee that bottom two graduated cylinder, liquid outlet 5 is closed, can not spill from bottom liquid outlet when liquid is poured into.Be placed on by two graduated cylinder on the groove 6 of support 8, fixing graduated cylinder, makes graduated cylinder can be placed on reposefully on experiment table under the supporting role of support.Pour the liquid that will measure into, after liquid is steady, level observes scale mark and liquid position carries out reading, after experiment, open funnel baffle plate 10, make liquid in graduated cylinder from the outflow of 11 mouthfuls, funnel, tilt to central lower by bottom two graduated cylinder inclination shape, the speed that such liquid arrives liquid outlet is just more accelerated, and does not also have the liquid carried in two graduated cylinder, that cleans is more thorough, and because bottom has support to support, the instruments such as measuring cup can be placed under funnel, liquid is flowed out, simple and convenient, swift to operate.The utility model is simple to operate, cheap for manufacturing cost, the capillarity occurred when graduated cylinder can be avoided to measure liquid, makes reading more accurate, increases the accuracy essence of experimental data, reaches experiment effect.
Claims (2)
1. a graduated cylinder, it is characterized in that: the right and left respectively has a graduated cylinder, connected by cored screw plug bottom two graduated cylinders, bottom centre has drainage hopper to be connected with funnel baffle plate, is furnished with bottom bracket, hold up stably in the left and right sides of two graduated cylinder, by the parallel pipe support of graduated cylinder both sides on the groove of support.
