Bottom Sampling Dredges
Bottom sampling dredges, commonly referred to as Van Veen grabs, and the Ekman dredge (or Ekman grab) are essential for collecting bottom sediment samples in aquatic environments. Our dredges are designed for precision and efficiency, making them ideal for environmental studies and water quality assessments. With durable construction and thoughtful engineering, they’re built to perform across diverse bodies of water, from freshwater lakes and rivers to coastal waters.
Bottom sampling dredges, including the Ekman dredge, are ideal for collecting sandy, silty, and muddy samples from soft-bottom environments with minimal disturbance to underlying layers. Each design features a unique triggering mechanism yet delivers dependable performance and consistent results for sediment sampling.
Whether you're conducting routine sediment analysis or working on a specialized project, our dredges provide the reliability and accuracy required for successful results.
