SuperSleeve "No-Purge" Grab Sampler

EON's SuperSleeve is a modified HydraSleeve No-Purge groundwater sampler that maximizes the amount of sample water acquired from a 2-inch well. It is used instead of the regular HydraSleeve when well screen length or water column is short and the amount of water required is greater than a standard HydraSleeve will produce.

The SuperSleeve is fitted on to a Top Collar Assembly which is very close in diameter to the inside diameter of a 2-inch well. The close fit causes nearly all the water in the sample zone to be captured by the sleeve during recovery. The Top Collar is available in a 2 piece PVC (non-weighted) version and as a 2 piece Top Weighted Collar with a stainless steel weight that causes the SuperSleeve to compressed as close to the bottom of the well as possible when deployed, leaving more screen length above the SuperSleeve available for sampling.

Check out the "Universal Heavy-Duty" (Skinny) SuperSleeves for use in Schedule 80 or 50-mm diameter well casing or where ever your 2-inch well is smaller diameter or slightly restricted. Same functionality, smaller diameter.

Simply lower the empty SuperSleeve sampler to the desired interval, let the well return to undisturbed conditions, and rapidly pull the sampler through the sample zone. The SuperSleeve seals itself when full, preventing overlying layers from entering and sampled contents from leaving the sampler.
