The horizontal Van Dorn water sampler is intended for taking water samples near the bottom in lakes, streams, or in stratified water bodies. The water sampler is based on the Van Dorn design. When the 2 rubber end covers are released, they are held together by a rubber strap.
The sampler is made of a sturdy transparent acrylic tube and has a double releaser, activated by a drop messenger. The release system is manufactured from AISI 316 stainless steel. The Van Dorn comes with the drop messenger. All Van Dorn models have been re-designed for better performance and now the steering fins are integrated into the sampler, ensuring a better stabilization in flowing water.
