Container bottle

The present invention relates to a container bottle, and more particularly to a container bottle provided with a connecting tube.

Due to the gradual development of biotechnology, different components of the blood can be used in different fields of medicine. In modern medicine, when blood is centrifuged, it is separated into a plasma layer, a buffy coat and a red blood cell layer from top to bottom, and the yellow turbid layer is composed of platelets, stem cells and lymphocytes. Among them, the skin color layer has a relatively high medical and commercial value, so at present, the method of how to separate the blood layer of the skin from the blood is often used to extract higher concentrations of platelets and stem cells.
