BX-750 Box Corer


The BX-750 box corer is ideal for deep water and ocean work. A stainless-steel box is used to reduce contamination and variable weight can be added to aid penetration, and the depth of penetration can be controlled to prevent over-penetration in
softer sediments.

Special features include:

  • automatic door closing device
  • pre-trip preventer bar with posi-action hook
  • quick release spade latches, and a jacking dolly for mounting and removing the sample box and spade.

This is a large box corer that requires a vessel large enough for deployment and transfer.


Material: Stainless Steel

Weight: 980 kilos

Height: 212 cm

Deck footprint: 200 cm X 250 cm

Box area: 75 cm X 75 cm X 60 cm

Category Description

Box Corers are used to sample soft sediments in lakes and oceans. The corer is lowered vertically until it impacts with the seabed. At this point the instrument is triggered by a trip as the main coring stem passes through its frame. While pulling the corer out of the sediment the spade swings underneath the sample to prevent loss. The recovered sample is completely enclosed after sampling, reducing the loss of finer materials during recovery. Stainless steel doors, kept open during the deployment to reduce any “bow-wave effect” during sampling, are triggered on sampling and remain tightly closed, sealing the sampled water from that of the water column. On recovery, the sample can be processed directly through the large access doors or via the removal of the box completely, together with its cutting blade.

A properly designed and operated box corer is suitable for collecting zoo- benthos (Gage & Tyler 1991, Paterson et al. 1998), surficial sediments (McCave 1985, Ekeroth et al. 2012) and surface concretions (Hessler & Jumars 1974, Veillette et al. 2007). A box corer can also be used for sub-coring to minimize core shortening or for taking replicate subsamples (Blomqvist & Bostròˆm 1987).
