Sediment Diffusion Sampler

Sediment Diffusion Sampler

The Equilibrator Sediment Diffusion Samplers are used to obtain representative concentrations of VOCs in saturated sediments or in stream beds, ponds, etc. This is an easy and reliable method for monitoring recharge and discharge areas including embankments, stream beds, pond sludge where a monitoring well is not installed. 

The Equilibrator can be buried directly in sediments or used with our protective canister screens in sediments or streams where physical conditions or debris could otherwise damage the sampler alone.

Special sizes and configurations are available. For more information on passive diffusion sampling click here. 

Select Equilibrator sampler from below based on sample volume requirements. 

Select Canister to accommodate sampler length.
