Description of Solinst Model 800 Low Pressure Packers Groundwater Samplers

In order to stop soil gas or groundwater from mixing at a specific depth in a well or borehole, pneumatic packers are employed to isolate a distinct zone. The isolated zone is then the only focus of subsurface investigations. Packers are inflated to close off the distinct zone at the appropriate depths. A straddle packer can be used to establish a secluded area between two packers, or a single packer can be used to monitor the zone above or below it.

About of Solinst Model 800 Low Pressure Packers Groundwater Samplers

Solinst Low Pressure Pneumatic Packers are available in two diameters, as single or straddle packers primarily for use in 2″ to 5″ monitoring wells (50 and 125 mm). They can be inflated using a hand pump to a maximum of up to 50 psi (345 kPa). Solinst Packers are designed to temporary, low-pressure applications to monitor soil gas and groundwater.

Ideal for isolating discrete zones for:

Groundwater sampling and monitoring
Minimizing purge volumes
Reducing well development time
Slug and pump tests
Hydraulic conductivity testing

These simple inexpensive packers inflate with a hand pump and are available in 1.8″ and 3.9″ (46 mm and 99 mm) diameters. Primarily for short term use in 2″ and 4″ (51 mm and 102 mm) monitoring wells, they can also be used in smooth boreholes and wells with 1.9 – 5″ (48 – 127 mm) inside diameters. Typical inflation pressures for the 1.8″ (46 mm) packers are from 20 – 40 psi (140 – 275 kPa) above hydrostatic pressure, and from 20 – 30 psi (140 – 205 kPa) for the 3.9″ (99 mm) packers.

The Packers utilize a gland of black carbon reinforced rubber (BCR) on a Sch 80 PVC body. They are lowered on a support cable or a rigid PVC drop pipe. If a rigid drop tube is not required for your application, it is recommended to attach a safety line to the eyebolt provided. The Solinst Model 103 Tag Line provides a convenient, graduated support cable that can be used for this purpose, as well as for measuring placement depth. The inflation line is standard LDPE tubing and connects to the Packers using a simple push fitting.

The 800M Mini Packers are 1 ft. (305 mm) in length and 1.8″ (46 mm) in diameter, available in single or straddle packer setups. They are designed for falling head tests, and work easily with the Solinst Model 415 12V Pump to isolate groundwater sampling zones and reduce purge volumes in nominal 2″ OD wells. They are also useful when multiple, shorter well intervals need to be isolated, e.g. during aquifer testing.
