Niskin Sampler
The Niskin Sampler (also known as the Van Dorn Bottle) is designed for collecting water samples at various depths. Its horizontal design makes it ideal for sampling in stratified waters or areas with strong currents. Available in five sizes, it ensures minimal metal contact with the sample, preserving sample integrity.

Overview
The Niskin Sampler is designed for precise water sampling in both shallow and deep waters, ideal for collecting samples in stratified or current-influenced environments.
Key Features & Benefits:
✔ Horizontal Design: Ensures optimal sampling in stratified waters and areas with strong currents.
✔ Transparent Acrylic Body: Provides clear visibility of the sample for instant assessment.
✔ Reliable Plug Mechanism: Features plugs connected by a latex band that remain open during descent for smooth water flow.
✔ Controlled Sample Retrieval: Each plug is equipped with a tap for easy and precise sample extraction.
✔ Versatile Sizing: Available in five sizes to suit various sampling volume requirements.
✔ Metal-Free Interior: Ensures sample purity by eliminating metallic components inside the bottle.
✔ Efficient Sampling Process: Descends horizontally and is pulled sideways before closing to capture water from targeted depths.
Applications:
Ideal for marine research, environmental monitoring, and water quality assessments.
Perfect for sampling narrow stratification layers, thermoclines, and bottom sediments.
The Niskin Sampler combines precision, durability, and user convenience, making it a trusted solution for aquatic sampling in diverse environments.
