In the experiment with SmartRack®, the necessary chemicals and materials were available directly at the workstation in the correct order. Pipette tips, gloves, tweezers and pipettes were neatly organised in the SmartRack®.
The use of imprecise pipettes, contaminated or incorrect materials can affect the smooth running of enzymatic reactions. For example, the use of talcum-coated gloves and their entry into the sample can affect enzymatic activity. Double distilled water is required for dilution series. The choice of module holders means that the chemicals and materials required for the experiment are available at the workstation in a standardised, ergonomic arrangement without having to search for them. The integrated storage box provides safe, contamination-free storage of samples while liquids are being added or the reaction is being observed. The tablet holder in the SmartRack® allows results to be digitised immediately, minimising transmission errors.
In the traditional, unorganised setup, obtaining chemicals, equipment and materials requires additional walking and searching. Unsorted pipettes, gloves and other materials create disorder, inefficiency and increase the risk of contamination. Traditional test tube or tube racks present a risk of instability and potential tipping. They cannot be stacked and take up a lot of workspace. There is little room for parallel experiments with additional materials and samples during reaction and waiting times.
