A manipulative laboratory device for transferring biological fluid from one or more primary containers to an associated secondary set of containers through a disposable closed compartment system. The compartment system allows for greatly simplified decanting procedures, for example, in pouring off serum samples in blood analyses. The transfer device is preferably of transparent plastic material, and allows for complete isolation among respective samples and selective transfer of controlled volumes of biological fluid when combined with a pump, through means to apply equal volumes of pressurized gas to each of the compartments. The transfer device allows, serum, for example, to be held and filtered during transfer, while maintaining the serum within a closed compartment to reduce the risk of hepatitis and similar infectious transmissions to operating personnel. In combinations with the disposable transfer device, a pressurization device and rack constructions are provided to facilitate gang handling of a plurality of biological fluid specimens, in one operation. |
