500mL HDS Bottle-Vac, Silonite Fitting, 24 Hr Sampler

Product Description

Using Helium Diffusion Sampling into Silonite® Canisters and Bottle-VacsTM for indoor air monitoring has never been so easy and cost effective! Introducing Entech’s low-cost external HDSTM Samplers that allow any Silonite® Canister or Bottle-VacTM to be used to perform time integrated sampling both simply and cost-effectively. HDSTM 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.
