All data are well organized in an integrated data base and can be shared with supervisors and colleagues if desired. The smart imager PAULA can be placed wherever needed- on the lab bench, under the hood and even in the incubator. This allows to monitor cells over time and to perform cell based assays like confluence evaluation. A smart user management enables PAULA to store and recall user specific settings and ensures reproducibility of results – thus enabling a profound standardization of the cell culture workflow.
