Van Walt is the exclusive distributor of the Snap Sampler in the UK and Ireland. The Snap Sampler is suited for most groundwater monitoring and sampling situations and also especially helpful in difficult conditions such as with low yield wells.
The Snap Sampler seals groundwater samples down well, in bottles that can then be directly analysed in a laboratory. The sample is never exposed to the open air and collection of the sample does not require pumps, controllers, meters and purge water waste containers. It is quick and easy to collect the samples and so can save money on sample collection costs.
The Snap Sampler with 40ml and 125ml bottles fits in 2-inch or larger monitoring wells. With 350ml bottles the sampler will fit in 4-inch or larger monitoring wells.
Snap Sample bottles are loaded into the Snap Samplers, set open, deployed for a period of time — usually all the way between sampling events — are "snapped" shut downhole, retrieved, secured, and sent to a lab without opening them.
