Filter Apparatus

This is the filter they use to separate out their organism. Using different size filters allows them to filter out different grazers too - the critters that eat the phytoplankton. They keep these for studies of the relationship between the phytoplankton and the zooplankton. Zooplankton are one celled animals while phytoplankton are one celled plants.
