Housed in an aluminum framework, our Standard Berlese Funnels are lightweight (1.55 kilos including the aluminum frame) and easy to install (L36.5 x W36.5 x H52 cm after assembly). All parts are detachable and stackable. These funnels are very suitable for use in the wilderness and laboratories where there is no access to electricity.
Our Standard Berlese Funnel is designed so that it can be hung by strings (NOT included). To accelerate extraction of soil organisms, external heat sources (NOT included) can be easily attached to the aluminum frame.
Because the funnel (34-cm diameters, 35-cm high) is made of PE plastic, it has a very sleek internal surface and cannot be easily deformed. There is no risk of it getting rusty. The Standard Berlese Funnel uses a 50-ml Eppendorf tube as the bottom container for collecting extracted organisms. This Eppendorf tube can be removed and a beaker placed underneath the funnel when large extraction amounts are expected.
To hold soil or leaf litter samples, this Standard Berlese Funnel uses a 30-cm diameter PP plastic tray with apertures 7-mm in size. Filters of any smaller apertures can be placed on the tray. At the top of the funnel, a removable pop-up mesh lid (33.5-cm diameter) fits perfectly in the rim to stop critters from escaping or entering the soil and leaf litter samples. Because this top cover is of Polyester netting (96x26 mesh), there is good ventilation of humidity from the sample to the environment.
