1.4L HDS MiniCan™ Sampler (24 Hour)
SKU: 29-MC1400H24
Rather than performing a traditional vacuum sampling event, MiniCans and Bottle-Vacs™ are initially filled with helium, or helium with a recovery surrogate, and active sampling occurs in response to the controlled exchange of helium with air through a diffusion region.
