Cell Separating tube

The utility model relates to a cell separating tube which is improved and realized on the basis of the separating tube of the prior art. The utility model comprises the separating tube. The utility model is characterized in that the upper part of the separating tube is thick, the lower part is thin, and the separating tube is additionally matched with a big and a small cell filtering screens. The utility model has the advantages of simple structure, reasonable design, favorable cell separating effect, time saving and labor saving. Owing to the isolation action of the cell filtering screens, the utility model can effectively prevent a blood specimen to be separated from dispersing the liquid level of stratified liquid and mixing with the stratified liquid so that the limiting surface between the blood specimen to be separated and the stratified liquid is clear, and the specific gravity is unchanged. The cell separating tube can greatly improve the operating speed of cell separation.
