Airtight soil sample collecting and sealing

March 2, 2023  By Ground Water Canada

Q.E.D. Environmental Systems has introduced the En Core Sampler, which collects, stores, and delivers soil samples within a single, easy-to-use device. This disposable volumetric sampling device was developed to empower field personnel to take soil samples with minimal handling and maximum accuracy.

The one-use, self-contained, inert composite polymer sampling cassette is ideal for airtight sample collection and sealing. The airtight sealing cap prevents the loss of volatiles as the sampler becomes its own self-contained package. This allows the sampler to meet the EPA’s SW-846 Method 5025, which ensures accuracy when identifying the types and concentrations of volatile organic compounds (VOCs) in soils and solid materials via a closed-system purge-and-trap process.

The En Core Sampler is designed to be environmentally friendly, as no chemicals are involved in the field. In fact, the sampler eliminates the need for methanol and sodium bisulfate preservation. It also enhances accuracy by eliminating sources of lab discrepancies.


Available in five-gram and 25-gram options, this disposable sampler can serve in a variety of applications. It also comes with a reusable, 4.5-inch-long stainless steel En Core T-handle that allows the handler to push the sampler into the soil for a measured soil sample. The En Core Extrusion Tool is also available that can be used to engage the plunger and push the sample into an appropriate vial.

“The En Core Sampler plays an important role in our mission to empower the workers who serve our environment,” notes David Kaminski. “This is a best-in-class technology that helps get the job done in an efficient, accurate, and environmentally friendly capacity.”
