The work described here shows a way to use measured values from laboratory balances digitally, even if the devices are not connected to other systems via interfaces or networks. The proposed solution consisted of developing an app for mobile devices that enables the recording of readings, their conversion to digital values through image recognition, and the integration of this app into the functionality of an electronic laboratory book. By implementing different use case scenarios, the method could be adapted to necessary workflow steps in everyday laboratory life and different processes could be mapped when using the balances. The app and the ELN were able to map a completely digital process from the planning of a weighing procedure to the storage of the weighing result in the documentation. The advantages of this process are not only the avoidance of mix-ups and errors but also a high degree of transparency of the process and the possibility of verifying the weighing processes by storing the obtained weighing results in the form of the image and the value obtained from it. The developments described here show a way to overcome previous limitations in achieving digitalization in the laboratory. The solution shown for device integration here has been optimized for use of data from laboratory balances, but the components developed can be adapted to other processes and devices with little effort.
