Berlese funnels and Winker selectors are effective tools for separating leaf litter and humus from photophobic insects and arachnids. Three types available.

The standard Berlese Funnel (Catalogue #EBER), The Pop-up Berlese Funnel (Catalogue #EMBT) and the Tray-type Berlese Funnel (Catalogue #EBTRAY).

EBER: Standard Berlese Tunnel 34cm diameter (Refer Image 2 for photo)

This standard Berlese Funnel is housed in lightweight but sturdy aluminium frame. The funnel (34cm diameter, 35cm high) is made of PE plastic. It has a very sleek internal surface and cannot be easily deformed.

The EBER 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 (33.5cm diameter) fits perfectly in the rim to stop specimens from escaping or entering the soil and leaf litter samples. Because this top cover is of Polyester netting (96×26 mesh), there is good ventilation of humidity from the sample to the environment.

Other features:

• The unit is easily installed
• Can be used either in the field or laboratory.
• The 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  aluminium frame.
• Main Material: Plastic | Polyethylene
• Mesh Sizes: 96×26 | 680 um opening
• Measurements after assembly – L36.5 x W36.5 x Height 52cm
• Weight 1.55Kgs

EMBT: Pop-up Berlese Funnel 38cm diameter

This pop-up Berlese funnel is designed to let moisture evaporate naturally through the netting in the top compartment. Without requiring a heat source, it can extract soil-dwelling arthropods, especially when only a thin layer of leaf litter or humus is placed on the gauze.

Consists of five parts + carrying bag:

1. Top compartment; White nylon netting (104 x 94 mesh/square inch)to permit light to enter and moisture to quickly evaporate.
2. Gauze: Black Polyester netting (mesh aperture about 6 mm) sewn to foldable metal ring that holds Berlese funnel open.
3. Funnel: Bottom funnel is of black, smooth Nylon cloth.
4. Connector: The tube connector is of PE plastic and connects the funnel to the collecting tube.
5. Collecting tube; Eppendorf tube (50 ml)
6. Carrying Bag

• Dimensions: Folded 16cm diameter x 8cm thick.
• Lightweight: 310 grams.

Light bulb: Is not included but can be used as a heat source if required; simply clinch top opening around lamp socket base or place the heat source to shine into the funnel. When expected extraction amount is large, other containers (e.g. Whirl-Pak sampling bag, may be tied onto the connector.

EBTRAY: Tray-type Berlese Funnel (44cm diameter)

The tray-type Berlese funnel is designed to let moisture evaporate naturally through the netting in the top compartment. Without requiring a heat source, it can extract soil-dwelling arthropods, especially when only a thin layer of leaf litter or humus is placed on the tray.

Consists of six items + carrying bags:

1. Top compartment: White nylon netting (104 x 94 mesh/square inch)to permit light to enter and moisture to quickly evaporate.
2. Net filters: three (3) removable plastic netting (2×2, 3×3, and 6×5 mesh per inch, or 4×4, 6×6, and 11×9 mm in aperture size.
3. Tray: White plastic and cut into grille to hold net filters and soil samples.
4. Funnel: Nylon cloth.
5. Connector: The tube connector is of PE plastic and connects the funnel tray to the collecting tube.
6. Collecting Tube: Eppendorf tube (50 ml)
7. Carrying bag.

• Dimensions:
  • Tray: 37cm inner diameter; 43cm outer diameter; 5cm high.
  • Funnel: 44cm outer diameter; 95cm height without collecting tube.
• Lightweight: 500 grams.
• Tray is stackable

When expected extraction amount is large, other containers (e.g. Whirl-Pak sampling bag, may be tied onto the connector.

The bottom funnel is of black, smooth Nylon cloth. The tube connector is of 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.
