摘要： Described are pipette tips and methods of making the same. The pipette tips may include at least two components, an annular component and a tubular body component. The annular component may comprise a different and relatively more compliant material. The annular component may be partially or entirely telescopically received within the tubular body component. Alternatively, the annular component may comprise a proximal end of the pipette tip and the tubular body component may comprise a distal end of the pipette tip. A portion of the tubular body component may be telescopically received by the annular component or otherwise attached thereto. The pipette tip may be formed by first molding the annular component and next molding the tubular body component. Alternatively, the tubular body component may be molded first and the annular component may be molded within, adjacent, or about the tubular body component.
