Description

Technical Field

[0001] The invention relates to the technical field of general chemical or physical laboratory equipment, in particular to a test tube rack for temporarily storing veterinary drug suspension intermediates. Background Art

[0002] Most existing test tube racks are in a static state and cannot be shaken continuously. For some veterinary drug intermediates in the form of suspensions, such as sulfadiazine suspension intermediates and florfenicol suspension intermediates, when they are temporarily stored in test tubes, precipitation or stratification is prone to occur in a static state. If they are not shaken during storage, the particles may precipitate and agglomerate, making it difficult to disperse evenly, affecting the dosage accuracy during subsequent use. However, if a conventional test tube rack is placed on a shaker and the shaker is used to drive the test tube rack to vibrate as a whole, the shaking effect on the test tube itself is poor, and it is difficult to achieve the expected effect. In addition, the test tube rack needs to be stably fixed during the shaking process to prevent the test tube from tipping over. In addition, the introduction of a shaker also increases costs and floor space. Summary of the invention
