Abstract
The utility model discloses a test tube used for shelving inclined plane, belonging to the technical field of biological experiment equipment. The test tube includes a semispherical bottom and a cylindrate side wall, wherein, a position line is arranged on the cylindrate side wall of the test tube. The position line is constitutes by, from top to bottom, an inclined liquid-level top position line, a vertical liquid-level position line and an inclined liquid-level bottom position line. The utility model is for shelving the best inclined plane that meets the requirement, which means the inclined plane covers the semispherical bottom of the test tube, meanwhile, the length of the inclined plane reaches approximately to one half of the length of the cylinder part. Through the position line arranged at the corresponding place of the ordinary test tube, the utility model can indicate the optimal dose of the solid substrate that should be added to the test tube when the inclined plane is shelved. At the same time, the positions of the front end and the back end of the optimal inclined plane is also indicated. The utility model has the advantages of reasonable structure and convenient operation.
Description
Technical field
The utility model is a kind of inclined-plane test tube of shelving, and belongs to microbiology experiment equipment technical field.
Background technology
Shelving the inclined-plane is the microbiology experimental technique on a basis.This technology is to arrive certain angle by the inclination test tube, makes the solid medium in the test tube form a plane before cooling, and finally forms a solid culture base plane in vitro, to be used for follow-up microbiology experimental implementation.The suitableeest medium slant of this specification requirement must be full of the domed bottom of test tube, to prevent that in cultivation the inclined-plane is dry and cracked and to possess certain moisture; The length on inclined-plane should not surpass 1/2nd of test tube column part length simultaneously, with the pollution that prevents to take place in cultivation or operating process.In traditional operation, add the amount of culture medium and the shape on formation inclined-plane and all need experience control by experiment, thereby be difficult in experiment, accurately shelve out best inclined-plane.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, easy to operate inclined-plane test tube of shelving.
The utility model is achieved through the following technical solutions:
This test tube comprises domed bottom and cylindrical side wall, wherein, is provided with position line on the cylinder side wall of test tube.
Described position line is inclination liquid level top position line, vertical liquid level position line and inclination liquid level bottom position line from top to bottom.
The utility model is in order to shelve out satisfactory best inclined-plane, and promptly the inclined-plane is full of the domed bottom of test tube, and the length on inclined-plane is near 1/2nd of test tube column part length simultaneously.This invention is provided with position line by the corresponding site at common test tube, can indicate the optimal dose of the solid medium that in this test tube, should add when shelving the inclined-plane, indicate the position, front-end and back-end on suitable inclined-plane simultaneously, have advantages such as rational in infrastructure, easy to operate.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode figure.
Wherein, 1, position line, 2, liquid, 3, test tube.
The specific embodiment
Embodiment: structure as shown in the figure, this test tube comprises semicircular base and cylindrical side wall, is carved with position line on the cylinder side wall of test tube. position line is inclination liquid level top position line, vertical liquid level position line and inclination liquid level bottom position line from top to bottom.Concrete design is according to calculating, satisfactory cultivation base unit weight should be adding of test tube domed bottom volume and quadrant post partial volume and, remaining volume after the loss of deducting concave meniscus then and being brought.Wherein Kui Sun calculating need be analyzed according to the wetting capacity of different liquids in tube material, but because the wetting capacity of solid medium can be alternative with the wetting capacity of LB solid medium in the experiment of conventional microbiology.But because the material of test tube is different with bore, the formed concave meniscus height of LB solid medium difference wherein then, thereby when needing measure at first by experiment vertical placement, the formed concave meniscus height of solid medium in this test tube.The position of each position line is as follows:
The position of inclination liquid level top position line is 1/2nd of a column part length for the distance apart from the mouth of pipe;
The position of vertical liquid level position line is
L is the length apart from the test tube mouth of pipe, and a is a test tube column part length, and h is the formed concave meniscus height of LB solid medium, and d is the test tube diameter.;
The position of inclination liquid level bottom position line is at the boundary line of test tube column part and hemispherical bottom, and the graduation mark of rear end, promptly best inclined-plane is a column part length from the distance of the mouth of pipe.
Claims (2)
1. shelve the inclined-plane test tube, this test tube comprises domed bottom and cylindrical side wall, it is characterized in that, described test tube cylinder side wall is provided with position line.
2. the inclined-plane test tube of shelving according to claim 1 is characterized in that, described position line is inclination liquid level top position line, vertical liquid level position line and inclination liquid level bottom position line from top to bottom.
