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.

The KC water sampler can be used singly (by use of 1 pc 60.002 Centre hanger for single ocean water sampler) or in series and closes correspondingly. The Niskin water bottles are also available in a special version, (61.xxx series) which can only be used with our Rosette and Racks system.
