Benthic chamberHaps Operated by hand
50.820 - Haps corer operated by hand:
- Application:
- Sediment sampling in shallow lakes with a maximum depth of
approx. 4 m. Taking a good sample demands half-hard sediment.
General: - 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.
- Operation:
- 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.
- Delivery:
- Standard delivery comes exclusive core tube and sample ejection
aggregate (extruder) which must be ordered separately.
