Van Veen Grab for Sampling Soft or Medium-Hard Bottoms

Exploration of Aquatic Ecosystems with the Van Veen SG Grab

A high-precision solution for sediment sampling in fresh and salt water, ensuring sample integrity across diverse natural underwater substrates.

The Van Veen SG Grab is a professional-grade instrument meticulously designed for the study and preservation of aquatic nature. Engineered to collect sediment samples from soft to medium-hard bottoms—such as sand, gravel, consolidated marl, or clay—this system utilizes a sophisticated mechanical design to ensure high-quality data collection. Its two-jaw hinged structure maintains an open position during descent and triggers a powerful closing mechanism upon contact with the bed, capturing the biological and geological essence of the seabed without disturbing the sample stratification.

Highlighted Features

• Automatic locking mechanism ensures the grab remains open during the descent phase.
• Robust construction using AISI 316 stainless steel for maximum durability in saline environments.
• Integrated top windows for sample inspection or sub-sampling prior to full release.
• Dual-arm design provides the necessary leverage for a hermetic seal on consolidated substrates.
• Scalable options available in three sizes to accommodate various research sampling requirements.
