Niskin bottle NK
Designed for taking samples in the water column.
Sampling
Is designed for vertical sampling and facilitates a free flow of water through the bottle as it is towed. Manufactured in different sizes, its inside is free of metallic objects in order to maintain the conditions of the sample, which can be retrieved via the tap located at the bottom of the bottle.
Design
Its main body is formed of a tube, and the bottle has a plug at either end, connected by latex bands. The plugs are kept open during the descent, which facilitates the passage of water. The closure system, located on the side of the bottle, is activated by messenger at the desired depth.
Different uses
As well as being used individually, it can be used in series by attaching several bottles to the same line and operating their closure via messengers in cascade. This allows the collection of samples at various depths. It may also be used in oceanographic rosettes, with closure activated by the rosette mechanism.

Niskin accessories
Niskin centre hanger
When the bottle is used individually, the accessory “Niskin centre hanger” can be employed, which keeps the bottle upright at all times. With this mechanism, you can keep using our messenger to close the bottle.
Niskin replacements
Double latex band for Niskin
The new Niskin bottle includes a high-quality double latex band. Putting on and taking off this band is much easier than the previous version as it screws onto the two Niskin bottle plugs. It is available in several sizes depending on your Niskin bottle model.
