The OSIL Mini-Box Corer is a simple and reliable corer for sampling an area of 0.05 m2 of sediment with minimal disturbance and sample contamination.

It is a quarter scale version of the standard OSIL Box Corer. This ‘mini’ version is constructed of aluminium and stainless steel to reduce its weight, thereby allowing deployment from smaller boats in the inshore environment.

The Mini-Box Corer’s unique double shovel design allows easy access to the sediment for sub-sampling for subsequent scientific investigation. They are widely used for sampling in biological, chemical and geochemical applications as the relatively large block of sediment provides a large well preserved sample.

A Corer can be easily deployed from a deck stand and lowered onto a standard lifeboat no-load release, which activates after sediment penetration. The box is closed, top and bottom, by two closely fitting shovels, mounted on pivot arms. Removable weights allow the corers to be used successfully in a range of sediment types.
