They can differentiate into various different types of cells, such as cardiomyocytes, neurons, and vascular endothelial cells, etc. In medicine, stem cells have been used to treat many diseases, such as leukemia, Parkinson's disease, and diabetes, etc. A serum-free medium is a medium that does not contain animal serum components. It is usually composed of a basal medium, growth factors, hormones, vitamins, and trace elements, etc. Compared with the traditional serum-containing medium, the serum-free medium can avoid animal-derived contamination and some other problems, and is more convenient, efficient, and controllable. Usually, test tubes are used to store it.

[0029] Furthermore, the heat preservation sleeve 21 is sleeved on the outer surface of the tube body 11, and the material of the heat preservation sleeve 21 is set as a heat preservation material, so as to perform heat preservation treatment on the surface of the tube body 11 through the heat preservation sleeve 21.

[0030] Furthermore, the heat preservation sleeve 21 has elasticity itself to adapt to test tubes of different shapes, and the support ring 24 is supported at the bottom by the fixed frame 25 and the support base 26, so as to support the support ring 24 through the fixed frame 25 and the support base 26.

[0031] Further, an adjusting mechanism 3 is connected to the outer surface of the heat preservation sleeve 21. The adjusting mechanism 3 includes a fixing ring 31. Bearings 32 are connected to both sides of the fixing ring 31. One end of the bearing 32 is movably connected to a sliding rod 33.
