Problems solved by technology

[0003] The apertures of the fixed test tubes of the existing test tube racks are all fixed and cannot be adjusted. The aperture of each fixed test tube can only be placed with a test tube of a corresponding size, which is inconvenient to place test tubes of different sizes, and after placing the test tubes, Since the aperture of the test tube fixed by the test tube rack is larger than the aperture of the test tube, it will shake during the movement, which will easily damage the test tube and reduce the service life of the test tube

Abstract

The invention relates to the field of biological experiment teaching and provides a test tube rack for biological experiments. The height of a test tube clamping and fixing table can be adjusted to realize placement of test tubes in different heights; by spring clamping devices, the test tubes in different diameters can be fixed stably without shaking. The test tube rack comprises a supporting fixing device, a height adjusting device, a test tube clamping and fixing device and a damping protection device. The height adjusting device is fixedly mounted at the left end of the supporting fixing device, the test tube clamping and fixing device is movably mounted on the height adjusting device, and the supporting fixing device is internally provided with the damping protection device. The testtube rack for the biological experiments has advantages that the test tubes in different diameters can be stably fixed to the test tube rack without shaking, and accordingly the utilization range of the test tube rack for the biological experiments is expanded while service lives of the test tubes are prolonged.

Description

technical field [0001] The invention relates to the technical field of biological experiments, in particular to a test tube rack for biological experiments. Background technique [0002] The test tube rack is the most basic experimental instrument in the chemical laboratory used to place (sometimes the test tube can also be placed on the test tube rack to observe the phenomenon of a certain experiment) and dry the test tube. A corresponding number of small wooden columns and small holes are attached to the test tube rack. If there is a small hole, the test tube can be placed upright for use or in order to continue to observe the progress of the reaction. If there is a column, the clean test tube can be turned upside down for drying. [0003] The apertures of the fixed test tubes of the existing test tube racks are all fixed and cannot be adjusted. The aperture of each fixed test tube can only be placed with a test tube of a corresponding size, which is inconvenient to plac...
