The Van Dorn / Niskin Bottle allows samples to be taken at different depths of water. The horizontal design of the bottle makes it ideal for sampling in stratified waters or areas with predominant currents.
It consists of a transparent tube with plugs at either end, connected by a latex band. The plugs are kept open during the descent, which facilitates the passage of water. Each plug has a tap so the sample can be retrieved.
Manufactured in 5 sizes, according to the sampling volume its inside is free of metallic objects to maintain the conditions of the sample.
Intended for shallow or deep waters, these bottles are called “horizontal” because they descend horizontally, parallel to the bottom, and are pulled sideways about one meter before closing. This ensures a representative water sample for specific depths. They are ideal for sampling narrow stratification layers, especially at the thermocline, or just above the bottom sediments. These popular and versatile bottles come in transparent acrylic which allows you to view the bottle contents immediately.
