The Box Corers are simple and reliable corers for sampling an area of 0.25m² of sediment with minimal disturbance and sample contamination. Its unique double shovel design allows easy access to the sediment for sub-sampling for subsequent scientific investigation. Box corers are widely used for sampling in biological, chemical and geochemical applications as the relatively large block of sediment provides a large well preserved sample.

​The corers are easily deployed from a deck stand and lowered on 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.
