This dedicated, in-well equipment is deployed at the desired position in the screen interval with up to six Snap Samplers and six individual sampling bottles. The design allows for the collection of groundwater samples which are in dynamic equilibrium with the aquifer through a simple, no purge/passive technique. Advantages: No-Pump, No-Pour groundwater sampling is faster and generates no purge water waste. All critical actions take place submerged in the well, which limits the impacts of: heat, wind, rain, surface contamination, or off-gassing losses Improved sampling consistency since variations in site conditions from season-to-season or changes in personnel from event-to-event do not affect the sample collection process. There is no heavy equipment to carry and no drums to move.

The MicroPurge MP10 Controller (U.S. Patent Number 6,508,310) revolutionizes low-flow ground water sampling with advanced logic control of purge flow and well drawdown. Simple up-down arrow keys increase and decrease purge flow to meet low-flow requirements. Once optimized, settings can be easily recalled in the next round of sampling.

The MP15 (U.S. Patent Number 6,508,310) MicroPurge Backpack combines advanced low-flow control with the quiet power of a built-in compressed gas source, for the ultimate in portability and ease of use in sampling ground water with bladder pumps. The MicroPurge MP15 (U.S. Patent Number 6,508,310) Controller revolutionizes low-flow ground water sampling with advanced logic control of purge flow and well drawdown. Simple up-down arrow keys increase and decrease purge flow to meet low-flow requirements. Once optimized, settings can be easily recalled in the next round of sampling.

Limiting drawdown is one of the basic requirements of proper low-flow sampling. The MicroPurge® MP30 (U.S. Patent Number 6,456,201) Drawdown/Water Level Meter provides a unique and simpler way to assure proper drawdown control. The MP30 switches between two modes- as a drawdown sensor and control when connected to the MicroPurge basics controllers, and as a high quality water level meter.

QED has combined its rugged and reliable fan-cooled 12 VDC air compressor with the time-proven QED MicroPurge Basics controller to provide an "all-in-one" package. Expert flow and drawdown control for low-volume purging and air compressor - all in one. The MP50 also offers an easy way to prevent excessive monitoring well drawdown during purging, by linking to the optional MP30 Drawdown/Water Level Meter.

Well Wizard pumps for MicroPurge low-flow groundwater sampling systems come in an unsurpassed range of sizes, materials, and capabilities, including models for deep sampling wells, narrow or obstructed casings, and small-volume pumps for low-yield monitoring wells. Together with MicroPurge controllers, flow cells, and accessories, they create the most reliable, cost-effective low-flow groundwater sampling system available.

The Sample Pro pump and tubing are and have always been PFC-Free. The Sample Pro Portable Pump, the first pump developed specifically to bring the advantages of low-flow sampling to sites requiring portable pumps, has been shown to be PFC-Free. Sample analysis by an independent laboratory showed no detections for 24 different perfluorinated compounds at detection limits much lower than the US EPA Health Advisory of 70 nanograms per liter (parts per trillion).

QuickFilter cartridges are the original ground water sampling filter for field use, developed to meet the stringent purity requirements of sensitive ground water quality monitoring programs. When sample filtration is required, disposable QuickFilter cartridges are easier to use, faster, and provide more consistent results than other filtration methods. When used directly in-line with a proper sampling pump, QuickFilters cartridges provide additional benefits of eliminating sample alteration due to air contact and/or sample quality changes with time and temperature.

The 3020 Compressor is a useful option for low-flow sampling of wells at depths to 200 feet. It runs on a 12 volt DC electrical supply, and can be connected to your vehicle`s battery with the supplied cables, or driven by a separate power source. At just 15x11x6-1/2" and 15 pounds, it offers an extremely convenient, portable pneumatic power choice for many sampling systems.

Unique, All-in-one Design Senses Water at the Pump. QED’s new Power Pro ESPTM low-flow electric sampling pump (patent pending) has an all-in-one design with user friendly controls built into the reel. You won’t need a heavy AC generator – just run the Power Pro off your vehicle’s battery, or go mobile in the field using a portable 12 VDC battery. The ESP Communications ProtocolSM provides simple pump operation with sophisticated control. The In-Water Sensor lights up when the pump is submerged, making it easy to position the pump in the well. The Run-Dry Protection limits drawdown and prevents damage to the motor and seal.
