Used to sample for soil arthropods. Can be used with fumigants or heat. Large plastic funnel (21-cm diam) allows a large sample to be taken. Funnel includes plastic collecting vial, hardware cloth insert, and plastic funnel support.
A soil sample is placed into a funnel positioned over a container of alcohol. Heat is used to desiccate the sample from above. As the soil begins to dry, small invertebrates in the sample move downward, eventually falling into the container of alcohol where they die and are preserved. These invertebrates can then be studied.
