A biology laboratory system comprising: a first storage module for storing cell culture plates (100,122) and a second storage module (100,122) for storing lab-ware or liquids, wherein each storage module comprises a housing, a working deck located within said housing, and a first microplate configured to carry biological material such as cell cultures, a second microplate configured to carry a liquid, a third microplate configured to carry a pipette tip box, wherein: the working deck having at least a first, second and third working deck microplate slots for receiving at least one of the first, second and third microplate in the first, second and third microplate slot, respectively, wherein the working deck microplate slots are radially arranged with reference to a center axis of rotation of the working deck, a liquid handling robot comprising at least one pipette for aspirating the liquid, a first transfer interface being in communication with the first storage module for the first microplate, at least one second transfer interface being in communication with the second storage module (100, 122), wherein the working deck is movable between a plurality of working positions, wherein in a first of the working positions the first microplate is located under an operating point of the liquid handling robot, wherein in a second of the working positions the first microplate is in alignment with said first transfer interface for transfer of the first microplate between an outside of the housing and the working deck microplate slot, wherein in a third of the working positions at least one of the second or third microplate being received by the second and the third of the working deck microplate slots is in alignment with said first or at least one second transfer interface for transfer of the second or third microplate between an outside of the housing and the working deck microplate slot, wherein the liquid handling robot is configured to be moveable in a plane running parallel to a rotational plane of the rotatable working deck to different working deck plate microplate slots to aspirate liquid from the second microplate located at the second working deck microplate slot and transport the liquid to the first microplate located at the first working deck microplate slot and configured to grasp tips from the pipette tip box located at the third working deck microplate slot. a first storage module for storing cell culture plates (100,122) and a second storage module (100,122) for storing lab-ware or liquids, wherein each storage module comprises a
