ABSTRACT:
A disposable laboratory device for transfer of fluids, such as biological fluids or reagents, to specific wells of a centrifugal analyzer head. The device itself is a disposable, multi-compartmental system within an arcuately extending enclosure. In the preferred embodiment, the enclosure extends in a circular arc of approximately 120.degree., whereby one-third of the wells arranged around a circular centrifugal analyzer head can be filled with a single manipulation. Each of the compartments is preferably trapezoidal in plan view, with a bottom surface that includes an outlet means for each compartment proximate radially innermost portions of the enclosure. Equal volumes of pressurized gas distributed to each of the compartments exactly dispense equal volumes from each of the compartments into wells in a circular analyzer head which is held in a registration position. In combination with the disposable transfer device itself the present invention includes a rack specifically constructed to facilitate registration of the analyzer head with respect to the disposable enclosure, and pivoting of the enclosure into its horizontal operating orientation.
