This simple Berlese apparatus was designed to study the biodiversity of the microfauna of a soil with the whole class. Insects and other nematodes contained in the earth flee light and fall into the alcohol.
This model is economical, compact and very practical.
The magnifying lid replaces the funnel and allows you to observe insects, nematodes and other living organisms isolated by the experiment. The grid allows you to differentiate size scales between isolated organisms.

It consists of:

• A transparent plastic pot with a grid engraved in the bottom to measure the size of the elements observed. (diameter x Height) 74 x 66 mm
  
• A funnel (Max. Diam. 140 mm)
  
• A mesh preventing the soil from falling to the bottom of the pot
  
• A lid with a magnifying glass, two magnifications 2 x and 3.5 x.
