The Tullgren Funnel is an apparatus which helps to remove living organisms from leaf litter. Leaf litter is placed in a filter funnel which is covered with black paper. The funnel is then held over a bottle containing a mixture of alcohol and water. There is a piece of gauze present to prevent soil entering the liquid. Once the leaf litter has been placed in the funnel, the apparatus is put under a strong light for at least two weeks. The soil dries out slowly and this encourages the living organisms to move downwards.
