Groundwater Sampling Accessories

solinst model 800 low pressure groundwater packers

The Model 800 Low Pressure Packers are convenient and easy to use. They are ideal for isolating discrete zones for various groundwater sampling and monitoring applications.

The Packers are designed for pneumatic inflation at pressures from 20 - 50 psi; inflatable with a hand pump. Single or Straddle Packers are available in two sizes, primarily used in 2" and 4" monitoring wells, or in smooth boreholes and wells with 1.9" - 5" inside diameters.

Solinst Packers consist of a gland of black carbon reinforced rubber (BCR) on an Sch 80 PVC body. They are lowered with little effort using flexible low-density polyethylene (LDPE) tubing or rigid PVC drop pipe; a Model 103 Tag Line can be used for extra support and for accurate deployment. The inflation line is easily attached using the nylon compression fittings on each packer.

 

solinst model 103 tag line for backfilling sand and bentonite layers

The Model 103 Tag Line was originally designed for use during the construction of monitoring wells, to measure the depth of a well or to tag a backfill layer of sand or bentonite.

The Solinst Tag Line uses a weight clipped to a polyethylene coated, permanently marked, stainless steel cable or laser marked PVDF flat tape. The cable/tape is mounted on a sturdy free-standing reel.

Because the weight is easily clipped off, the Tag Line can be used to deploy a number of different instruments, and because the cable/tape is marked, you can ensure you are getting your instruments to the proper depth.

This is excellent for bailer deployment. The Solinst Model 428 Disposable Bailers, Model 429 Point Source Bailers, and the Model 425 Discrete Interval Samplers, all have a convenient connector to securely attach a Tag line. Tag Lines can also be used to install Packers, and are great safety supports for downhole Bladder Pumps or Double Valve Pumps.
