A pipette tip member has an elongated tubular receptacle including a sidewall with a plurality of stabilizing projections extending from the sidewall for aligning the pipette shaft, and a sidewall with a bifurcated section that includes first, second, and third sidewall portions. The first sidewall portion defines a base wall and the second and third sidewall portions branch therefrom. The second sidewall portion is an outside branch wall, and the third sidewall portion is an inside branch wall spaced substantially parallel with and radially inward from the second sidewall portion. The inside branch wall is flexible in the radial direction and engages a pipette shaft when it is inserted into the receptacle and to form a fluid-tight seal therewith. A method of forming a pipette tip member is also enclosed.
