摘要: A pipette tip member having an elongated tubular receptacle having a sidewall with a bifurcated section that comprises first, second, and third sidewall portions. The first sidewall portion comprises a base wall and the second and third sidewall portions branch therefrom. The second sidewall portion comprises an outside branch wall, and the third sidewall portion comprises 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 tip 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 disclosed.

摘要: 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.

摘要: A pipette tip member having an elongated tubular receptacle with a protrusion on an inner surface of the receptacle, and a recess on the inner surface adjacent the protrusion. The tip member has a generally conical shape and the protrusion extends around the inner surface to form an annular sealing ring. The protrusion has a V-shaped axial cross section with edges that intersect at an angle between about 30° and about 120°. The recess has a generally circular axial cross section and the recess is disposed proximal to the protrusion in the axial direction. The recess depth is about as great as the protrusion height. A method of forming a pipette tip member is also disclosed.
