Haps Operated by hand

50.820 - Haps corer operated by hand:

Sediment sampling in shallow lakes with a maximum depth of approx. 4 m. Taking a good sample demands half-hard sediment.

The corer head is manufactured from AISI 316 stainless steel and mounted on a 4 m (2 x 2 m), O.D 28 mm stainless steel shaft with a solid assembly fitting.

It is very easy to mount the corer tube on a corer head securing with a spring-loaded mechanism.

A non-return flap is mounted beneath the corer head to ensure a good vacuum preventing the sample from exit.

During penetration the non-return flap and a shovel will be held open manually by a 5 mm polyester line.

After withdrawing the corer from the sediment, the hand held line has to be released and the non-return flap and the shovel under the corer tube will close.

Standard delivery comes exclusive core tube and sample ejection aggregate (extruder) which must be ordered separately.
