23.300 - Bongo net, 2 x 60 cm:

A bongo net consists of two plankton nets mounted next to each other. These plankton nets are ring nets with a small mesh width and a long funnel shape. Both nets are enclosed by a cod-end that is used for collecting plankton. The bongo net is pulled horizontally through the water column by a research vessel. Using a bongo net, a scientist can work with two different mesh widths simultaneously.

1. V-Fin Depressor made of cast brass, weight 18 kg (optional).
2. Wire Ø6 mm stainless steel with shackle (optional).
3. Double net ring Ø60 cm diameter, made of AISI 316 stainless steel with 1 loop in the middle for wire and V-Fin depressor and 2 loops for an optional digital counter located in the middle of the opening.
4. AISI 316 stainless steel clamping fíxture.
5. Two conical nets, Ø60 cm upper diameter, Ø11 cm lower diameter, consisting of Monodur Nytal (PA6.6 nylon). Standard delivery includes 300 µm + 500 µm. Length of 250 cm. Other mesh sizes upon request. Within 100 - 500 µm there is no additional cost.
