[0002] The supercoiled DNA separation and purification column test tube rack is a tool used for DNA separation and purification in molecular biology experiments. It is usually made of plastic or metal and has a series of vertical holes for placing test tubes. These test tubes are usually used to contain a mixture of DNA samples and solvents, which are separated and purified by the filler (usually silica gel or silica gel) in the column.

[0003] After searching, a separation and purification column test tube rack with announcement number CN202778558U was found, which includes a test tube rack body, and the test tube rack body is provided with a liquid storage tank for receiving residual liquid. Water droplets on the surface of the test tube fall into the liquid storage tank, which is convenient for centralized disposal and helps to keep the laboratory environment clean.

[0004] The above patent mentioned that "water droplets on the surface of the test tube fall into the liquid storage tank, which is convenient for centralized treatment and is conducive to keeping the laboratory environment clean". However, in the actual use process, the water droplets on the surface of the test tube can fall into the liquid storage tank, but the height of the test tube rack cannot be adjusted. The inability to adjust the height of the test tube rack may mean that it cannot adapt to test tubes of different heights or lengths, which may limit the design and execution of the experiment, especially when test tubes of different sizes are required. Therefore, in response to the above problems, a supercoiled DNA separation and purification column test tube rack is proposed. Utility Model Content
