Abstract
The utility model discloses a kind of test tube of overturning-preventing, comprise bottom body, the mouth of pipe and test tube, also comprise test tube base, test tube base center is provided with and the cylinder shape groove matched bottom test tube, cylinder shape groove mouth is provided with elastic ring, 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 test tube cap comprises the connecting ring, flexible connecting member, top cover and the inner cap that are fixed on body, and inner cap is positioned at top cover centre and matches with the mouth of pipe, and top cover is fixedly connected with connecting ring by flexible connecting member.The advantage of this test tube is, test tube base stablizes test tube, without the need to rack for test tube, saves lab space; Test tube bottom outer wall is cylindrical, and bottom interior wall is that the structure of back taper effectively prevents from crashing bottom test tube, makes a small amount of product accumulation be convenient to draw at the bottom of pipe; Body is provided with graduation mark, conveniently measures solvent and reactant.
Description
Technical field
The utility model relates to and belongs to experiment equipment field, especially a kind of test tube of overturning-preventing.
Background technology
Test tube, as the instrument that chemical laboratory is conventional, can as the container of little quantitative response, but current test tube all cannot measure solvent volume, makes troubles to test operation.In addition arc-shaped structure bottom it, cannot independently place, and bottom easily breaks up, and causes reactant or product to spread out.When reaction mass is few, bottom arc-shaped structure cannot make reactant concentrate, and affects reaction rate.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of test tube of overturning-preventing, can concentrate reaction mass, can also prevent bottom test tube broken.
The technical solution adopted in the utility model is: a kind of test tube of overturning-preventing, 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 cylinder shape groove matched bottom test tube, described cylinder shape groove mouth is provided with elastic ring, 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 the connecting ring, flexible connecting member, top cover and the inner cap that are fixed on body, and described inner cap is positioned at top cover centre and matches with the mouth of pipe, and described top cover is fixedly connected with connecting ring by flexible connecting member.
Described body is also provided with graduation mark.
Described body is provided with test tube handle.
The beneficial effects of the utility model: test tube base can stablize test tube when adding reactant, without the need to rack for test tube, save lab space; 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 graduation mark, conveniently measures solvent and reactant; Test tube handle facilitates test tube to pick and place.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of test tube of overturning-preventing, to comprise bottom body 2, the mouth of pipe 1 and test tube 3, also comprise test tube base 4, test tube base 4 center is provided with and 3 cylinder shape grooves matched 13 bottom test tube, cylinder shape groove mouth is provided with elastic ring 14, test tube base can stablize test tube when adding reactant, without the need to rack for test tube, saves lab space, elastic ring can make test tube more stable, and making needs stable test tube diameter can have floating of certain limit.
Test tube bottom outer wall 7 is cylindrical, and test tube bottom interior wall 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 test tube cap comprises the connecting ring 9, flexible connecting member 10, top cover 11 and the inner cap 12 that are fixed on body 2, and inner cap 12 is positioned at top cover 11 centre and matches with the mouth of pipe 1, and top cover 11 is fixedly connected with connecting ring 9 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.
Body 2 is also provided with graduation mark 5, conveniently measures solvent and reactant
Body 2 is provided with test tube handle 8, facilitates test tube to take.
