To switch the spectrophotometer on and off, click on the
switch
When you click on one of the reagent bottles, the cap will open; from that moment, the pipette will draw from that reagent.
When you click again on the bottle or its cap, it will be capped.
Trick: while a bottle remains open, it is enough to hover the pointer over the pipette to have this filled up again.
To add an aliquot of a sample to a cuvette:
- Select a cuvette clicking on it or on the radio button below it.
- Click on the pipette.
To empty a cuvette, select it and then click on the waste vessel.
To access the cuvette compartment, click on the latch or on the cover.
To introduce a cuvette into the spectrophotometer or to get it out:
- Select a cuvette clicking on it or on the radio button below it.
- Click on one of the arrows
- (Beware that the compartment cover must be open)
Action of buttons and icons:
records the measurement in the external monitor
records a spectrum
clears all information off the monitor
captures an snapshot of the spectrum, which can then be copied or saved via the context menu in the browser
represents the waste disposal vessel; when clicked on it, the selected cuvette will be emptied
The pipette delivers 1 mℓ aliquots. Each cuvette has a 3 mℓ capacity; if surpassed, it will spill (the cuvette will then be emptied in order to continue). To be measured in the spectrophotometer, the cuvette must contain at least 2 mℓ of sample.
The absorbance reading displays ##### whenever it is not possible to measure: if the compartment cover is open or if the volume in the cuvette is not enough.
