Abstract:

The problem of plastic waste in research laboratories is a significant one, with an estimated 5.5 million tonnes generated annually worldwide. Reusable labware has the potential to reduce this waste significantly, but the design of such products must take into account quality assurance to guarantee the accuracy of experiments. Insights were gathered through the generation of an overview of the available techniques for verifying labware after use and decontamination. As during different design cycles verification of prototypes is needed, these techniques were evaluated and translated to be applicable in the specific context of a design lab. Therefore, this study presents a protocol which can be used as a verification tool while designing safe, reusable labware for chemical laboratories. This protocol consists of four different steps: (i) visual inspection, (ii) mass & size comparison, (iii) leak test, and (iv) chemical stability test.
