Methods and devices for the preparation of a biological pharmaceutical composition outside of a classified environment, such as Biological Safety Cabinet type environment, are described. In one aspect of the present technology, a method is provided to prepare a biological pharmaceutical composition preferably in an area next to a patient's bedside or at a facility's pharmacy. The method comprises transferring an appropriate amount of a diluent from a diluent component (645) into a mixing receptacle (605) using a transfer device (620), connecting a pooling (630) harness between a biological pharmaceutical component (640) and the mixing receptacle, transferring a biological pharmaceutical composition through the pooling harness to the mixing receptacle, mixing the diluent and the biological pharmaceutical composition to form a biological pharmaceutical composition mixture and administering the biological pharmaceutical composition mixture to a patient for either flat based or weight based dosing needs.
