Grab

This hefty center-pivot sampler is designed to sample unconsolidated sediments from soft ooze to hard-packed silts from deep lakes and near offshore.

• Center pivot for undisturbed samples
• Scoop volume: 3000 mL
• Stable on bottom slopes of 20° or more
• For deep lakes and near offshore
• Single rotating jaw scoop
• Automatic release
   

 It brings up virtually un- disturbed, unwashed samples to the surface from any depth. Its specialty is sampling benthic organisms living at or immediately below the water/bottom interface and sediment containing a significant population of non-sessile forms.

The current Shipek® is based upon the patented design of the late Carl J. Shipek, noted oceanographer, and is manufactured by Wildco® under license. It consists of two concentric half cylinders, the outer of which is the sampler body. A cocking wrench, included, is used for winding the torsion springs. A safety hook prevents their premature release when held in the safety position. Cast into each end of the frame are large stabilizing handles which, along with its weight, hold the sampler upright during descent.
