This is the second part of a two-part video. In this video, we first look at how to create a dilution series to be used to make a calibration curve for glucose concentration. We then explore how to use a colorimeter to measure the absorbance of the solutions and how to use the calibration curve to determine the concentration of glucose in an unknown solution.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
