Fenwick Can

The Fenwick Can is the most commonly used instrument for the extraction of cysts from soil samples using the principles of flotation. The can tapers toward the top, with a slopping collar around the outside of the rim which collects overflow and directs it towards an outlet. The can has a sloping internal base with a drain plug at its lowest point. Soil is placed at the bottom of the can. Water is then turned on and enters through a device that creates a swirling action in the bottom of the can. As the can fills, lighter soil particles and nematodes flow over the spout and onto one or more sieves from which nematodes are ‘backwashed’ after approximately two to five minutes.
