A stirring system for stirring contents in a laboratory flask having a round or spherical bottom and a reduced neck includes a stirrer shaft manufactured with a ring at the lower end thereof which permits attachment of a blade with a nut and bolt made of TEFLON material. The nut and bolt prevents the stirrer blade from flipping over during assembly and allows for a controlled tightening force to be applied to ensure that the blade remains in proper stirring position during use. The nut and bolt design permits use of the shaft with any stirrer blade having a keyhole cutout or circular opening. A method of stirring contents in a laboratory flask by attachment of the stirrer blade to the stirrer shaft with a nut and bolt is also disclosed.
