Wildco K-B Series Heavy Corer with 20-inch Tube

Obtain Quantitative Samples in Demanding Environments with This Stainless Steel Corer

The K-B Heavy Corer with Case is your specialized tool for collecting sediment and fauna samples in deep water, especially at the water-bottom interface. Its design, optimized for obtaining samples of mobile benthic organisms like Tubificidae, incorporates a valve that remains open during descent, preventing pressure waves that might alert fauna. The messenger-activated closure allows you to control exactly when to capture the sample. This heavy version offers better penetration into compact substrates and comes fully equipped with a messenger, a 100-foot line, a rigid carrying case, and a liner kit.

 Features

• It is ideal for deep water, recommended for sampling at depths over 300 ft (100 m).
• Its free-flow design minimizes sediment disturbance and does not alert fauna.
• It offers you total control with its messenger-operated closure system to trigger sampling at the exact moment.
• Its heavy version allows for more effective penetration into compact bottoms.
• It features a 316 stainless steel head and tube for high durability in marine environments.
• Its components are interchangeable with other Wildco® corers.
• The complete kit includes a messenger, a 100 ft. line, a rigid case, liners, and core catchers.

Wildco Shipek Type Sediment Dredge with 3 L Volume

Center-Pivot Design for Undisturbed Samples in Compact Sediments

This powerful center-pivot dredge is designed for you to sample sediments ranging from soft to compact in deep lakes and near-shore areas. It allows you to transfer undisturbed samples to the surface from any depth, without washout. Its specialty is sampling benthic organisms living at or just below the water-bottom interface, including non-sessile forms.

Based on the patented design of oceanographer Carl J. Shipek, this dredge consists of two concentric half-cylinders. To operate it, you use the included arming wrench to set the torsion springs. A safety hook prevents premature release. Its large stabilizing handles, along with its weight, keep the dredge upright during descent, ensuring accurate sampling.

Features

• Its center-pivot design ensures you get undisturbed samples, minimizing bottom disturbance.
• Allows you to collect a large 3-liter sample volume in a single operation.
• Its stable design, with large handles, allows you to use it even on slopes up to 20°.
• Features an automatic release mechanism that triggers upon impact with the bottom.
• Made of 316 stainless steel for maximum durability and corrosion resistance.
• Covers a sampling area of 0.04 m² with a bite depth of up to 4 inches.
