ABSTRACT:
A safety pipette is characterized in that an openable seal (6) is present within the pipette, necessitating the use of a forcing element (9) to hold the seal in an open position in order to use the pipette. Pipette inserts provide the seal in standard pipettes. Pipette adaptors provide the necessary forcing element. Pipette supports or nosepieces for pipetting devices are modified with a pipette adapter (8) allowing the use of safety pipettes. The forcing element is a pin, or rod, firmly made part of a nosepiece, or an adaptor that moves a flap or ball within a pipette away from a closed position into an open position, allowing air flow through the safety pipette. Kits comprise modified nosepieces or replacement elements thereof with safety pipettes per se, or with safety pipette inserts, and kits comprise pipette adaptors with safety pipettes or safety pipette inserts.
