Whether constructing your own suspension tethers or adding spare parts we can supply all the items (and advice) needed for a successful Diffusion Sampler Installation. Below are the most frequently used accessory parts for quick reference.
We supply ASTM Type I de-Ionized water for filling the Equilibrator Passive Diffusion Sampler, for cleaning and rinsing equipment, and for other environmental applications. Click Here to see all our options for De-Ionized water.
The Equilibrator & the .75-inch Passive diffusion Samplers can easily be filled in the field using one of our Fill Kit funnels. Match the Kit to the sampler size.
Discharge straws are supplied with every Diffusion Sampler order. Need More?
Passive sampling installations require the use of a stainless steel reusable weight to pull the suspension tether into place in the well. The Standard and Extra-Heavy Weights are used for most installations. Click Here to go to our complete list of Weights.
Snap Connectors and Zip-Ties are used on every Passive Sampler installation to attach samplers and weights to the tether and tethers to the well cap.
Suspension Rope or Cable
We recommend poly braided rope for all suspension tethers. Contact us for installation details when stainless steel cable is required.
Tether Winding Reel
Use this reel when retrieving PDBs from the well to keep the tether tangle-free and dirt-free. Especially useful for stainless tethers. Click Here to go to our complete list of Reels.
Diffusion-resistant pouches provide a barrier to VOCs when shipping or storing pre-filled passive diffusion samplers. Pouches features a sealable flap. Storage pouches are for samplers 18 to 24 inches long.
Well Caps with Hanging Ring
We recommend attaching Suspension Tethers to the underside of the well cap. Our most popular caps are shown below and have a 1-inch ring for this purpose. Click Here for complete complete list of well caps.
