Ballchek Corer 2416 B25
Automatic check valve creates strong seal Not for water/bottom interface Versatile: ideal in water 3 to 200 meters deep Simple, reliable design
Product Description
The Ballchek gravity corer is ideal for both shallow and deep water from 3 to 200 m in those instances where the water/bottom interface is not part of your study. At its heart is a simple seal that prevents the sample from leaving the tube during retrieval. A semirigid silastic ball, securely held by a tough, resilient polyurethane ring seat, automatically seals the top of the core tube as it is raised. All parts that contact the sample are made of inert plastic. Both the silastic ball and ring seat easily slide out for cleaning when the core tube is removed.
