Multi-range quantitative transfer pipette

The utility model provides a multi-range quantitative pipette, which relates to an instrument for chemical experiments, and comprises a pipette main body and a sharp nozzle, the pipette main body is provided with N cavities, and the outer surface of a thin glass tube at the upper part of each cavity is provided with corresponding scales; n > = 2; in the direction from the sharp mouth to the pipette main body, the volume of the latter cavity is not smaller than that of the former cavity; the volumes of the N cavities are the same or the volumes of the N cavities are different; when N is equal to 2, the scale combination corresponding to the two cavities is 5mL + 10mL, 10mL + 10mL, 25mL + 50mL and 50mL + 50mL; and the volumes of at least two of the N cavities are the same. The single-range transfer pipette is simple in manufacturing process and convenient and fast to use, and solves the problems that a plurality of traditional single-range transfer pipettes need to be matched for use in actual use, the operatio
