Bottle-Vac – Helium Diffusion Sampling

Product Description

Using Helium Diffusion Sampling into Silonite^TM Canisters and Bottle-Vacs^TM for indoor air monitoring has never been so easy and cost effective! Introducing Entech’s low-cost external HDS^TM Samplers that allow any Silonite^TM Canister or Bottle-Vac^TM to be used to perform time integrated sampling both simply and cost-effectively. HDS^TM utilizes a simple diffusion zone to control the exchange rate of helium and air, with diameters that are 20–50 times larger than typical critical orifice samplers, making particulate plugging virtually impossible.
