Passive Diffusion Samplers

HydroTerra sell the passive diffusion bags in three sizes; 150ml, 350ml and 500ml. PDS are great, affordable samplers used to determine VOCs in groundwater monitoring wells. Simply fill the bags with de-ionised/distilled water, install down the well and leave until the concentration gradient equilibrates in the bags. 

We can also provide bailer twine, weights and ex-caps for deployment in groundwater monitoring bores. If you would like more information on prices and stock availability please contact us on:
