Test tube oscillation device for laboratory analysis and testing

Abstract

The invention discloses a test tube oscillation device for laboratory analysis and testing, which comprises a device main body and a second test tube rack, a first test tube rack is arranged at the upper part in the device main body, the second test tube rack is arranged right below the first test tube rack and is arranged in a guide rail, the guide rail is fixedly mounted below the interior of the device main body, movable pins are arranged on the four sides of the bottom of the second test tube rack, connecting rods are fixedly installed in the movable pins, the other ends of the connecting rods are movably installed on movable plates through the movable pins, and the movable plates are arranged in the device main body. According to the test tube oscillation device for laboratory analysis and testing, test tubes of various types can be fixed, the multiple test tubes can be oscillated at a time, the practicability of the device body is improved, meanwhile, the device body can oscillate in a reciprocating motion mode in multiple horizontal directions, and the amplitude of the test tubes during oscillation can be changed; and therefore, the oscillation uniformity is ensured, and the detection accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of experimental analysis, in particular to a test tube oscillation device for laboratory analysis and testing. 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 an experiment) and dry the test tube. The test tube rack is equipped with a corresponding number of small wood Columns and small holes, if there are small holes, the test tube can be placed upright for use or to continue to observe the progress of the reaction, if there is a column, the cleaned test tube can be placed upside down for drying. [0003] During laboratory analysis and testing, it is often necessary to mix various reagents in the test tube, and then vibrate to observe the chemical reaction between the drug and the reagent in the test tube. At present, this vibratio...

Problems solved by technology

[0005] The object of the present invention is to provide a test tube oscillation device for laboratory analysis and testing, to solve the problem of manual completion by the inspectors proposed in the above-mentioned background technology. Long-term detection often causes serious soreness in the arms of the tester, and it is difficult to ensure the uniformity of the test tube if the test tube is shaken artificially for a long time, which affects the accuracy of the test, and the existing shaking device can only use A horizontal reciprocating motion oscillates. For some samples with high viscosity, the effect of oscillating and mixing is not very good, resulting in a large error in the test results.
