2″ X 2 Litre HD Universal Supersleeve


Larger diameter sleeve for maximum fill rate and maximum volume

SKU: GI HDSS - 2L Category:



  • Larger diameter sleeve for maximum fill rate and maximum volume.
  • Use in conjunction with the special 2-piece top weight.
  • Compresses to approximately 24 inches from the bottom of the well.
  • Disposable
  • Standard material virgin poly
  • Made for 2-inch schedule 40 wells — will not work in 2-inch schedule 80 or European 50mm wells.

*Distance the sampler needs to move upward to fill completely. The top of the sampler marks the beginning of the sample interval.

**Average distance from the top of sampler to the bottom of the well when compressed by the top weight. Sleeve is lowered into the well fully extended below the weight, not rolled and inserted inside the weight.

Sampler Length 60″
Weight Type 1.9″ OD top weight (24 oz.)
Minimum Well Diameter 2″ Schedule 40
Pull to Fill Distance* 2 L in 5″
Compressed by Top Weight** ~24″

Waterra’s HydraSleeve is a new way to collect discrete interval samples. With no need to purge or dispose of purge water, this groundwater sampler reduces your costs by saving time.

  • Long or short term groundwater monitoring
  • Samples low-yield wells
  • Determines dissolved contaminant fraction
  • Samples crooked or constricted wells
  • Vertically defines contaminant concentrations or composites sampler from 10′ screen interval

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.


HydraSleeve is suitable for both short and long term groundwater monitoring and is especially useful in narrow, constricted or damaged wells.

Cost savings of HydraSleeve sampling (typically 50 to 75%) make it the option of choice for monitoring UST leaks, dry cleaning plants and other small scale point-source contaminant sites. It can even be used for special challenges such as in-well vertical profiling of multi-layered contaminant concentrations.
