Abstract
The utility model relates to an automatic zeroing titration apparatus, which belongs to the field of experimental devices, in particular to an improvement of the automatic zeroing titration apparatus. The automatic zeroing titration apparatus has simple structure and is capable of replenishing solution quickly and automatically zeroing. The automatic zeroing titration apparatus comprises a burette, a conduit and an extrudable container with a perforated plug, wherein one end of the conduit is arranged on a zero point in the burette, and the other end of the conduit is led into the extrudable container through a hole of the plug. The automatic zeroing titration apparatus has quite simple structure and quite low cost, is easy to be popularized, and can lead standard liquid to flow into the burette by squeezing the extrudable container; when liquid level in the burette passes the zero point, and redundant standard liquid can be sucked into the extrudable container, thereby achieving the purpose of quick and easy replenishing and automatic zeroing.
Description
Technical field:
The utility model belongs to the experimental provision field, but relates in particular to the improvement of the titration apparatus of a kind of automatic zero set (AZS) position.
Background technology:
Buret can calculate the content of certain material according to the volume of quota of expenditure solution as the most frequently used glass apparatus of physico-chemical analysis, and each sample of titration needs to replenish standard solution again in buret, and is transferred to zero-bit.Cumbersome, efficient is low, the waste standard solution.
The patent No. is that 200610027250.X discloses a kind of auto-titration control device, and its advantage is can control many titration apparatuss simultaneously to carry out titration, and can control the speed and the amount of titration;
The patent No. is 200610027251.4 to disclose a kind of photoelectric automatic titration device, and its advantage is to control the speed and the amount of titration, does not need to concentrate on looking on always and examines.
The device construction of above-mentioned two publications is more complicated all, and cost is higher, does not have well to solve automatically the problem of make-up solution and automatic zero set (AZS) position fast.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of simple in structure, automatic zero set (AZS) titration apparatus of make-up solution and automatic zero set (AZS) position fast is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises buret, conduit, has the squeezable container of bottle stopper with holes, and an end of conduit is arranged on the place at zero point in the buret, and the other end of conduit leads in the squeezable container by the hole of bottle stopper.
As a kind of preferred version, an end of described conduit can lead to the bottom of squeezable container by bottle stopper with holes.
As another kind of preferred version, described squeezable container is in plastic containers, the rubber container.
The beneficial effects of the utility model:
The utility model structure is very simple, cost is very low, be easy to promote, and by the extruding squeezable container, allow normal fluid flow in the buret, when the liquid level in the buret surpassed zero point, unnecessary titer was known from experience sucked back in squeezable container, replenished fast easily and the purpose of automatic zero set (AZS) position thereby reach.
Description of drawings:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment:
The utility model comprises buret 5, conduit 3, has the squeezable container 2 of bottle stopper with holes, and an end of conduit 3 is arranged on 0. 4 places in the buret 5, and the other end of conduit 3 leads in the squeezable container 2 by bottle stopper with holes.
One end of described conduit 3 can lead to the bottom of squeezable container 2 by bottle stopper with holes.
Described squeezable container 2 is in plastic containers, the rubber container.
Below in conjunction with accompanying drawing a course of action of the present utility model is described:
The utility model is placed on the experiment frame, fills standard solution 1 in the squeezable container 2, an end of conduit 3 is arranged on 0. 4 places in the buret 5, and fixing with the geometrical clamp on the experiment frame 6; The other end of conduit 3 directly leads to the inner bottom part of squeezable container 2 by bottle stopper with holes; Extruding squeezable container 2, standard solution 1 flows in the buret 5 fast by conduit 3, when liquid level surpass buret 5 0. 4 the time, unclamp extruding, by the suction of squeezable container 2 self, unnecessary standard solution 1 refluxes by conduit 3, when liquid level arrives 0. 4, the normal fluid 0. 4 below 1 in the buret 5 can sucked back squeezable container in, thereby finished the process of fast additional standard solution 1 and automatic zero set (AZS).
