ABSTRACT:
A continuous flow centrifuge adapted with an insert of glass beads, sand or the like is used to concentrate cysts of microorganisms such asgiardiaorcryptosporidiumfrom large volumes of water. The apparatus and methods are useful for the detection of contaminating microoorganisms in groundwater and public drinking water.
