Colorimetry is a vital technique in chemistry and biology. It is, however, underused in schools due to the cost of the machines.
This workshop shows you how to construct and use a simple colorimeter using easily accessible materials at next to no cost. It is possible to get some good results from these and the cost is only about 70p per colorimeter and they can be constructed in about 15 minutes.
