Abstract: A culture flask has a flask body. The flask body has two translucent planes, one opening end, one recess end and at least one collecting recess. Both translucent planes are located on the opposite ends of the flask body. A collecting recess is formed on the inner surface of the recess end, while the cross sectional area of the recess end gradually decreases toward the bottom of the collecting recess. By forming a collecting recess with decreased cross sectional area, culture cells can be collected inside the bottom after centrifugation, and therefore the user no longer has to transfer the culture cells and culture medium to a centrifuge tube when replacing culture medium. Consumption of suction tube and centrifuge tube can be avoided, the time to replace the culture medium is reduced, and also the risk of contamination when replacing the culture medium is reduced.
