<p>57 An enclosed pipette tip rack comprises a container (12) having a bottom (14) and a side wall (15) extending upwardly to terminate in a top (16). A tray (22) is supported by the container (12), e.g. by shoulder (90), and holds at least one pipette tip (26, 28) such that a portion of the pipette tip lies within the container (12). A cover (30) is also provided and is supported by the container (12) adjacent the tray (22). Means are provided for venting the enclosure (32) formed by the container (12) and the cover (30) to the ambient environment so that sterilising fluids can circulate therethrough during autoclaving or other sterilisation processes. For example, the cover (30) may have ribs (40, 42, 44) which, in one orientation of the cover (30), are supported by the top (16) of the container (12) so that a gap remains between cover and container, while in another orientation of the cover (30) are located in recesses (46, 48, 50) in the container top (16) so that the cover fits tightly onto the container for dust-free storage of pipette tips. Alternatively, openings (56, 58, 60, 64) may be provided in the container (12) and/or the cover (30), or a slidable cover may be provided.</p> |
