The Surber Sampler is designed for quantitative sampling when the current is equal to or less than 10cm/second. The frame for the Surber Sampler is made from aluminium alloy and riveted for strength. The nylon screens reduce the loss of animals from around the mouth of the net, whilst folding flat for easy transport. The Surber Sampler Frame is available in three sizes: Small, Medium and Large.
Dimensions Medium Frame:
The high quality net bags are to fit the medium sized surber frame. They connect to the frame by threading onto an inner brass ring which attaches to the outer frame using a series of brackets, held in place with nuts and bolts. This means that the net collar is protected from rubbing on the river substrate by the outer frame; this considerably reduces wear and tear. The collar is made from strong nylon which also helps to improve longevity. The end of the open net is fitted with a removable screw-on filter which has the same mesh size as the main part of the net.
Available with closed end with 53µm, 100µm, 250µm, 500µm and 1mm mesh.
With open end and filter: 250µm, 500µm and 1mm mesh
