Unlike any other groundwater sampler, the HydraSleeve instantaneously cores a whole water sample from a defined vertical and horizontal interval (usually within the well screen). HydraSleeve samples do not blend fluid from different vertical zones or pull water in from outside the well screen, but instead sample via ambient and/or diffusive flow of groundwater through the well screen.
The sample is collected at in-situ pressure without purging and with very little down well disturbance, preventing turbidity, aeration or oxidation of sensitive parameters. Samples collected with the HydraSleeve correlate well to other sampling methods.
HydraSleeve samplers are inexpensive, disposable and very quick and easy to use, resulting in significant savings on capital equipment and operating costs when compared to other sampling equipment.
