Apparatus for even illumination in algal growth tests
article
For their growth algae largely depend on a good supply of light. In laboratory tests with algae, light always plays an important role. Many laboratories use monocellular algae for performing toxicity tests. Some of these species tend to cling to the walls of the culture bottles on the side of the light source, thus preventing the light from penetrating the whole culture. To get an even illumination of a whole series of test bottles, the authors constructed a device which is called the 'alga mill'. The idea behind this device originates from a method of storing algal cultures, and the algal mill has been used mainly for growth experiments with monocellular marine algae. A description of the apparatus is presented in this report. Different growth experiments performed on the alga mill have shown good reproducibility.
