A system for managing of bulk liquids and/or bulk solids for in-vitro diagnostics is disclosed. The system comprises a sample processing unit and a container unit for receiving a supply container supplying the sample processing unit with a bulk liquid/solid and/or a waste container receiving waste from the sample processing unit. The system further comprises a weight measuring device comprising a loading plate, a base and a force measuring cell. The force measuring cell comprises a sensor comprising a tensioned sensor wire. The loading plate is biased with respect to the base by a weight applied to the loading plate by a container and to transfer force to the force measuring cell. The transferred force causes a deformation of the force measuring cell and a change in tension of the sensor wire causing a change in vibrational frequency resulting in a signal indicative of the weight of the container.
A system for managing bulk liquids and/or bulk solids for in-vitro diagnostics, the system comprising:
The system according to claim 5, wherein the electronic device receives identification data from the non-volatile memory chip and confirms identity of the weight measuring device and/or calibrates the weight measuring device based on the identification data.
The system according to claim 9, wherein the closure mechanism comprises a closure sensor to detect closure of the bulk container and the position of the pipe in the bulk container.
The system according to claim 11, wherein the closure mechanism comprises a brush-like structure, or flexible elastomeric material, arranged around the pipe and achieves closure of the bulk container such as to prevent spilling of bulk liquid from the bulk container while keeping the pipe in place into the bulk container.
