Tray-type Berlese Funnel (Ø30 cm) [pack of 3]

Our tray-type Berlese funnel is designed to let moisture evaporate naturally through the netting in the top compartment.  It can rapidly extract soil-dwelling arthropods without requiring a heat source, especially when only a thin layer of leaf litter or humus is placed on the tray.  This makes the tray-type Berlese funnel an efficient tool for locations without electricity.  Because it is lightweight (320 grams) and the tray is stackable, many can be packed for field trips.

Each tray-type Berlese funnel consists of five parts: top, tray, funnel, connector, and collecting tube.  The top compartment is of white Nylon netting (104 x 94 mesh/square inch) to permit light to enter and moisture to evaporate quickly.

The tray is made of grey plastic and cut into a grille (7 mm sieve opening) to hold soil samples.  The bottom funnel is black, smooth nylon cloth.  The Eppendorf tube connector is PE plastic and connects the funnel to a collecting tube.  Each tray-type Berlese funnel comes with one Eppendorf tube (50 ml) for collection containers.  When the expected extraction amount is large, other containers (e.g., Whirl-Pak® sampling bag, NOT sold at the BugDorm Store) may be tied onto the connector.

The fast-release design of the tube connector permits the cleaning of overlooked specimens from the bottom opening.
