WATER SAMPLER
Niskin Water Sampler
The water sampler is fully made of PVC and its interior is totally free from metal parts. Top- and bottom plates are held together with a sea water resistant rubber string, and a drop messenger releases the closing mechanism. Because of the open construction during the deployment, the Niskin bottle can be used at any depth.
Van Dorn Water Sampler
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.
