General

The KC box corer frame is manufactured from 50 x 50 x 4 mm square AISI 316 stainless steel tube with a finish of electro polish. The sample tube (3) is made of 4 mm electropolished AISI 316 stainless steel.

Areas of sample tubes available are:

600 cm²: 29 x 20,7 cm

1000 cm²: 34,5 x 29 cm

The main racks for 600 cm² and 1000 cm² are identical and by changing some items you have the availability of both sizes.

Penetration depth of both tubes is 40 cm.

Function

During descent, insertion and sampling, the top of the sample tube remains open allowing a free flow of water. This prevents pressure build-up and following disturbance of the sediment surface.

After landing on the seabed, and the sample tube has reached its maximum depth, an automatic mechanism releases the closing shovel. The shovel is drawn into vertical position so that the bottom of the tube is closed and the sample is kept inside.

On withdrawal from the seabed, the top of the sample tube is closed and sealed by a hinged flap with a soft rubber packing.

A complete KC BOX CORER includes a frame (1), six lead weights and a standard sample tube (3) with sealing flap, inner shovel and closing shovel.

A special sample tube with an additional removable front plate and adjustable drainage holes, is available on request.
