How To Use A Colorimeter A Level Biology Aqa. Grind sample using a pestle and mortar and place into a chilled isolation. Use tongs to take the boiling tubes out of the water bath. Determining unknown glucose, starch, protein concentrations. Place boiling tubes in a water bath at 90°c for four minutes. Counting bacteria or yeast populations. Determining unknown glucose, starch, protein. They can be used when: Remove stalks from leaf samples. A colorimeter is able to measure light absorbance (how much light is absorbed) or light transmission (how much light passes through) a substance. In this method the named variable is light intensity. Use the contents of the 0.0 mmol dm −3 glucose solution tube, which you have heated with benedict's, as a blank to calibrate the colorimeter to zero absorbance. They can be used when: Counting bacteria or yeast populations. Zero the colorimeter using a cuvette with distilled water. Use a colorimeter to measure the absorbance of a series of solutions of known concentrations to create a calibration curve.
