Pneumatic Packers are used to isolate a discrete zone in a well or borehole to prevent the mixing of soil gas or groundwater at that particular depth. Subsurface investigations are then focused on the isolated zone only. At the desired depths, Packers are inflated to seal off the discrete zone. This can be done using a single Packer, to monitor the zone above or below it, or a straddle Packer set up to create an isolated section between two Packers.
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
The 800M Mini Pneumatic Packer is also available to fit nominal 2" OD monitoring wells. It is lightweight and only 1ft in length. It is ideal for connecting to the Solinst 12V Submersible Pump and for use during falling head and other aquifer tests.
The Solinst 12V Submersible Pump provides an efficient means of purging and obtaining groundwater samples from 2" OD monitoring wells. The compact pump can sample from depths of 36.5 m (120 ft) below ground surface, and is easy to adjust the flow rates up to 13.5 L/min (3.6 US gpm) in shallower applications.
The Levelogger 5 is an absolute precision water level and temperature recording device, which features 0.05% FS accuracy, 10-year battery, schedule sampling and memory for up to 150,000 sets of readings. PFAS-free PTFE coating makes it ideal for use in corrosive environments.
Connect a Solinst Bladder Pump or Double Valve Pump to a single or straddle Packer setup. Packers isolate discrete zones, which minimizes purge volumes and allows depth-discrete groundwater samples. Ideal for identifying vertical distribution of contaminants in a well.
The Model 105 Well Casing & Depth Indicator detects metal well casing and measures total well depth using one probe – helpful when installing downhole equipment.
