Van Veen grab SG

Van Veen grab SG

To sample sediment.

How it works

The Van Veen grab SG is designed for collecting sediment samples in fresh and marine water, from soft or medium-hard bottoms like sand, gravel, consolidated marl or clay. It consists of two buckets connected by a hinge. During the descent, the two buckets remain apart. When it hits the bottom, the locking mechanism releases, and when the main line is pulled to retrieve the grab, the buckets close allowing the collection of the sample.
