The sample is placed in a container with a base made from gauze with a mesh designed to hold soil particles but permit the animals to pass. The container is arranged over a funnel – with a light above. The heat causes the animals to move away from the top of the sample – through the gauze sheet and into the funnel from which they can be collected. Used to extract small invertebrate animals from a dry soil sample. Most species are collected after two hours – but complete extraction takes two-three days.
