The Ballchek core sampler allows for both shallow and deep water core sampling applications. It is a gravity type sampler that comes with a stabilizing fin. The Ballchek comes standard with a 2" diameter, 36" long stainless steel sampling tube. It is not considered a complete flow through sampler and should not be used where the water-bottom interface is important to sample. The stabilizing fin is made of non-corrosive PVC which offers both high strength and low drag characteristics.
The Ballchek sampler has a simple, positive sealing mechanism which acts as a check-valve and prevents the sample from leaving the core tube during raising operations. Check-valves are made of tough, resilient polyurethane for long life and excellent service. All parts that come in contact with the core sampler are made of inert plastic.
