[0002] Vortex oscillator, also known as vortex shaker, is one of the indispensable equipment in the laboratory. It is widely used in colleges and universities, scientific research and production enterprises in many fields such as molecular biology, biochemistry, pharmaceuticals, environmental monitoring, petrochemicals, and food. Its technical application range covers multiple mixing solution steps in laboratory basic research and production processes such as cell culture, DNA / RNA extraction, and protein purification.

[0003] When the device drives the liquid in the test tube or other container to rotate, the liquid will form a vortex-like oscillation, thereby achieving the purpose of uniform mixing of the solution. By adjusting the rotation speed and position of the eccentric ring, the speed and direction of the vortex flow can be controlled. However, during the use of the existing vortex instrument, the operator is required to place the test tube or centrifuge tube on the carrying tray of the vortex instrument. During the vortex oscillation process, the operator needs to hold the test tube or centrifuge tube in his hand all the time. If a long-term oscillation is required, it is necessary to hold it in his hand for a long time, which causes inconvenience to the operator. Although the existing test tube support rack can solve the technical problem of the operator holding the test tube for a long time, when test tubes of different specifications need to be oscillated, different test tube support racks need to be replaced to achieve this, resulting in a waste of cost and affecting work efficiency.

[0004] Therefore, how to provide a test tube support rack with a simple structure, which can support test tubes and is applicable to test tubes of different specifications and a vortex instrument having the same, is a problem that technical personnel in this field need to solve urgently.
