Abstract

A shield is provided which is adapted for use in protecting a capillary pipette of a pipette assembly. The shield includes a hollow tubular body closed at one end and open at the other end. The open end of the shield is designed for removably mounting the shield on a pipette assembly with the capillary pipette thereof in protected position in the hollow tubular body. The body is formed at the closed end to facilitate use of the shield as a puncturing device. A shoulder is intermediate the ends of the body to provide a stop for preventing over extension of the closed end when used as a puncturing device and providing an engaging surface for the open end of another shield when at least two shields are nested together. When nested, the closed end of one shield extends into the open end of the next shield. By use of the shoulder and the configuration of the outer surface of a shield body, the degree of nesting is controlled and ease of removal of each shield for use is facilitated.
