Abstract
The utility model discloses a kind of test tube of improvement, comprise bottom body, the mouth of pipe, test tube, with test tube base, test tube base center is provided with and the cylindrical hole matched bottom test tube, elastic ring is provided with in through hole, tube wall is arranged with hydrops groove near mouth of pipe position, and described test tube bottom outer wall is cylindrical, and test tube bottom interior wall is back taper.The advantage of this test tube is, the test tube base with cylindrical hole can stablize test tube, and the elastic ring in through hole can protect test tube and base, and the hydrops groove of tube wall avoids the chemical reagent of side leakage to the corrosion of test tube base; Test tube bottom outer wall is cylindrical, and bottom interior wall is that the structure of back taper both can ensure not contact desktop bottom test tube, effectively prevents from crashing bottom test tube, and a small amount of product accumulation can also be made to be convenient to draw at the bottom of pipe.
Description
Technical field
The utility model relates to and belongs to experiment equipment field, especially a kind of test tube of improvement.
Background technology
Test tube, as the instrument that chemical laboratory is conventional, can as the container of little quantitative response, but current test tube when adding chemical reagent in test tube, is easy to side leakage occurs, if corrosive chemical reagent, will bring potential safety hazard to operating personnel.In addition arc-shaped structure bottom this test tube, cannot independently place, and bottom easily breaks up, and causes reactant or product to spread out, and the smooth easy landing of tube wall is broken into pieces.
Utility model content
For solving the problems of the technologies described above, the utility model provide a kind of improvement test tube, can independent holding test tubes, the chemical reagent of side leakage can also be avoided to damage experimenter.
The technical solution adopted in the utility model is: a kind of test tube of improvement, comprise bottom body, the mouth of pipe and test tube, also comprise test tube base, described test tube base center is provided with and the cylindrical hole matched bottom test tube, elastic ring is provided with in described through hole, described tube wall is arranged with hydrops groove near mouth of pipe position, and described test tube bottom outer wall is cylindrical, and test tube bottom interior wall is back taper.
This test tube also comprises test tube cap, and described test tube cap comprises top cover and is positioned at top cover centre and the inner cap matched with the mouth of pipe, and described top cover is fixedly connected with the connecting ring near mouth of pipe place by flexible connecting member.
Described body is also provided with PH colorimetric card.
It is circular and the test tube handle being provided with frosted layer that described body is provided with end.
The beneficial effects of the utility model: the test tube base with cylindrical hole can stablize test tube, and the elastic ring in through hole can protect test tube wall, also can protect base not by the corrosion of the chemical reagent flowed down along test tube wall; The hydrops groove of tube wall, makes the chemical reagent of side leakage trickle in hydrops groove along test tube outer wall, avoids the corrosion to test tube base; Test tube bottom outer wall is cylindrical, and bottom interior wall is that back taper both can ensure not contact desktop bottom test tube, effectively prevents from crashing bottom test tube, and a small amount of product accumulation can also be made to be convenient to draw at the bottom of pipe; Body is provided with PH colorimetric card, conveniently contrasts detection in time to the acid-base value of reactant liquor; End is circular and is provided with the test tube handle of frosted layer, the test tube and can be anti-skidding of conveniently taking.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of test tube of improvement, to comprise bottom body 2, the mouth of pipe 1 and test tube 3, also comprise test tube base 4 for stable test tube, test tube base 4 center is provided with and 3 cylindrical holes matched bottom test tube, and be provided with elastic ring 14 in through hole, body 2 outer wall is arranged with hydrops groove 5 near the mouth of pipe 1 position, test tube bottom outer wall 7 is cylindrical, and test tube bottom interior wall 6 is in back taper.Elastic ring 14 can make test tube more fastening, and the test tube diameter be suitable for can have floating of certain limit, can protect test tube wall in addition, also can protect base not by the corrosion of the chemical reagent flowed down along test tube wall.Hydrops groove 5 makes the chemical reagent of side leakage trickle in hydrops groove along test tube outer wall, avoids the corrosion to test tube base.Test tube bottom outer wall 7 is cylindrical, and the structure of inwall 6 in back taper, ensure that and do not contact desktop bottom test tube, effectively prevent from crashing bottom test tube, and a small amount of product accumulation can also be made to be convenient to draw at the bottom of pipe.
This test tube also comprises test tube cap, and described test tube cap comprises top cover 11 and is positioned at top cover 11 centre and the inner cap 12 matched with the mouth of pipe 1, and described top cover 11 is fixedly connected with the connecting ring 9 near the mouth of pipe 1 place by flexible connecting member 10.Test tube cap is clogged the mouth of pipe and form a closed container, the material of the inside can not scatter and prevent cross pollution, and after opening test tube cap, test tube cap, owing to being fixed on body by connecting ring, can not be lost.
Described body 2 is also provided with PH colorimetric card 13, conveniently in time detection is contrasted to the acid-base value of reactant liquor.
It is circular and the test tube handle 8 being provided with frosted layer 15 that described body 2 is provided with end, the test tube and can be anti-skidding of conveniently taking.
