Meets the new ASTM Standard D7929-14 for passive groundwater sampling
The Snap Sampler® collects a downhole water sample that can be tested for any chemical – there are no analyte limitations.
Snap Samplers capture undisturbed samples from a specific position in the well without agitation. Excellent for a high quality sealed sample, turbiditysensitive analytes (such as metals and many organic chemicals) and low yield wells.
Snap Samplers are dedicated (all water collected is utilized for sample analysis). Bottles are sent to the lab and replaced with fresh units during each sampling event.
No solid or liquid contaminated waste handling is required.

Formed in 1956, Geotech transitioned from a specialty machine shop to an environmental equipment manufacturer in 1978 when invited by the United States Geological Survey (USGS) to partner with them in developing products and technologies for the emerging U.S. Trace Metals Analysis Program.
As a result of this partnership, the bladder pumps, peristaltic pumps, 0.45-micron sampling filters, and filter holders developed by Geotech for the program became the groundwater industry standards.
Geotech rounded out already-extensive product lines by acquiring three outstanding companies: Oil Recovery Systems (ORS) in 1997, Keck Instruments, Inc. in 1999, and the Marschalk Corporation in 2005. Coupled with ongoing product research and development, Geotech today offers the most extensive line of equipment in the environmental field.
In addition to its 125,000 square-foot Denver-based manufacturing plant and corporate headquarters, Geotech now operates service centers in six other states, plus a European Sales Center in Barcelona, Spain and a representative office in Beijing, China. Geotech equipment meets environmental challenges on every continent!
