Probably the most widely used plankton trap today, it operates on the same principle as bottle samplers but is larger. Its water-clear, strong polycarbonate body minimizes avoidance reactions on the part of zooplankton while enabling you to sample at a specific depth. Stainless steel handles are mounted to sides and attach the trap to a line. Available in two sizes, although 30 L is recommended in Standard Methods.
