Abstract

The utility model discloses a quantitative reaction test tube which comprises a test tube body, wherein a sliding slot which is arranged along the height direction of the test tube body is arranged on an inner wall of the test tube body; a sliding element which is matched with the sliding slot is in sliding connection with the sliding slot; a reaction tube is fixedly arranged at the bottom of the sliding element; a plurality of draining holes are uniformly arranged on a side wall of the reaction tube; and a marking layer is arranged on the side wall of the sliding element. According to the technical scheme, a liquid reagent is added to the test tube body and a solid reagent is added to the reaction tube, so that a contact area between the solid reagent and the liquid reagent is controlled by controlling the height of the reaction tube, so as to achieve the purpose of controlling a reaction rate. Meanwhile, the marking layer is arranged on the sliding element, so that the reacting reagent volume can be accurately controlled by people.

Description

The quantitative reaction test tube

Technical field

The utility model relates to a kind of test tube, is specifically related to a kind of quantitative reaction test tube.

Background technology

At present, widely used test tube is made mainly with glass, uses this test tube can do the number of chemical experiment, but this test tube is when doing the solid-liquid combined experiments, all be that solid and liquid are directly dropped in vitro, be not easy to control reaction rate, can not control simultaneously and participate in the reaction quantity of object.

Summary of the invention

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of quantitative reaction test tube is provided, and it can control reaction rate and reacting dose effectively.

The technical scheme that the utility model adopts is: a kind of quantitative reaction test tube, comprise the test tube body, described test tube body inwall is provided with a sliding tray along the setting of test tube height direction, slidely connect a sliding part that cooperates with it in this sliding tray, this sliding part bottom is fixedly installed a reaction tube, evenly offer several small openings on the sidewall of this reaction tube, be provided with the scale layer on the sidewall of described sliding part.

As preferably, described sliding tray is T word groove, and described sliding part is the T word spare that cooperates with it.

The beneficial effects of the utility model are: because the utility model adopts such scheme, in the test tube body, add liquid reagent, in reaction tube, add solid reagent, people just can control by the height of control reaction tube the contact area of solid reagent and liquid reagent, thereby reach the purpose of control reaction rate, simultaneously at sliding part the scale layer is set again, people can accurately control the amount of reagent that reacts.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is A-A cutaway view among Fig. 1.

Among the figure: 1, test tube body; 2, sliding tray; 3, sliding part; 4, reaction tube; 5, small opening; 6, scale layer.

The specific embodiment

Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of quantitative reaction test tube, comprise test tube body 1, described test tube body 1 inwall is provided with a sliding tray 2 along the setting of test tube body 1 short transverse, slidely connects a sliding part 3 that cooperates with it in this sliding tray 2, and described sliding tray 2 is T word groove, described sliding part 3 is the T word spare that cooperates with it, these sliding part 3 bottoms are fixedly installed a reaction tube 4, evenly offer several small openings 5 on the sidewall of this reaction tube 4, are provided with scale layer 6 on the sidewall of described sliding part 3.

Because the utility model adopts such scheme, at test tube body 1 interior adding liquid reagent, at reaction tube 4 interior adding solid reagents, people just can control by the height of control reaction tube 4 contact area of solid reagent and liquid reagent, thereby reach the purpose of control reaction rate, simultaneously at sliding part 3 scale layer 6 is set again, people can accurately control the amount of reagent that reacts.

The above, it only is the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
