Abstract
The utility model discloses a kind of chemical experiment test tube, comprise bottom body, the mouth of pipe, test tube and test tube base, test tube base center is provided with and the groove matched bottom test tube, groove port is provided with elastic ring, test tube bottom outer wall is cylindrical, inwall is back taper, body is provided with color contrast band and the test tube handle with frosted layer, this test tube also comprises top cover and is positioned at top cover centre and the inner cap matched with the mouth of pipe, and top cover is fixedly connected with the circular protrusion near mouth of pipe place 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; By color contrast band, in course of reaction, can contrast in vitro color change at any time, can not be distinguish that the difference of look causes error because of people; Test tube bottom outer wall is cylindrical, and inwall 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; With the test tube handle of frosted layer, there is when picking and placeing test tube anti-skidding effect.
Description
Technical field
The utility model relates to and belongs to experiment equipment field, especially a kind of chemical experiment test tube.
Background technology
Test tube, as the instrument that chemical laboratory is conventional, can as the container of little quantitative response, but current test tube is arc-shaped structure bottom it, cannot independently place, and bottom easily breaks up, causes reactant or product to spread out.There will be following problem in addition: (1) a lot of all coloured change of chemical reaction, different people may have difference to the description of color.(2) test tube cannot measure solvent volume, makes troubles to test operation.(3) 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 one independently to place, and can measure volume and differentiate the chemical experiment test tube that reaction color changes.
The technical solution adopted in the utility model is: a kind of chemical experiment test tube, 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, and described body is provided with color contrast band.
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 inner cap, and described inner cap is positioned at top cover centre and matches with the mouth of pipe, and be provided with circular protrusion near mouth of pipe place, described top cover is fixedly connected with circular protrusion by flexible connecting member.
Described body is also provided with graduation mark.
Described body is provided with test tube handle, and the end of described handle is circular and is provided with frosted layer.
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; Body is provided with color contrast band, and in course of reaction, can contrast in vitro color change at any time, can not be distinguish that the difference of look causes error because of people; 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 is provided with frosted layer, has anti-skidding effect when picking and placeing test tube.

In figure, 1, the mouth of pipe, 2, body, 3, bottom test tube, 4, test tube base, 5, graduation mark, 6, test tube bottom interior wall, 7, test tube bottom outer wall, 8, test tube handle, 9, circular protrusion, 10, flexible connecting member, 11, top cover, 12, inner cap, 13, groove, 14, elastic ring, 15, color contrast band, 16, frosted layer.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of chemical experiment test tube, 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.
Body 2 is provided with color contrast band 15, and in course of reaction, can contrast in vitro color change at any time, can not be distinguish that the difference of look causes error because of people.
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, described test tube cap comprises top cover 11 and inner cap 12, described inner cap 12 is positioned at top cover 11 centre and matches with the mouth of pipe 1, and be provided with circular protrusion 9 near the mouth of pipe 1 place, described top cover 11 is fixedly connected with circular protrusion 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, and the end of test tube handle is circular and is provided with frosted layer 16, facilitates test tube to take, and has anti-skidding effect when picking and placeing test tube.
