K-B Corer Heavy Duty Head Assembly Only

[//img/descriptions/5350e05ca1762-moz-screenshot-5.jpg][//img/descriptions/5350e05ca2707-moz-screenshot-6.jpg] K-B Corer, Heavy, head assembly only, SS. * For deep water over 100 meters * For fauna at water/bottom interfaces * Can be free-dropped up to 10 m (33’) * In medium or heavy-duty versions * Unrestricted flow, little bottom disturbance * Messenger closing for more control * Parts interchangeable with Wildco® corers This design incorporates improvements by Dr. R. O. Brinkhurst, Institute of Ocean Sciences, specifically for obtaining quantitative samples of fast-moving Tubificidae. Because the valve is locked open during descent, there is minimal frontal wave and minimal warning to fauna at the water/bottom interface. It is messenger-operated and is under your full control: you can keep the K-B® open until you are sure you have a sample. The heavy K-B® affords better penetration. Units are also available without carry cases. Specifications: Heavy units weigh 16 kg (36 lb.) and include: * 316 stainless steel head assembly
