Well Wizard Bladder Pumps: The Original, Low-Flow Sampling Standard. 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. Field proven pump designs and an exclusive, high-performance PTFE bladder formulation offer the reliability critical to long-term monitoring. QED was first in the industry with a standard 10-year sampling pump warranty – "no-loopholes" protection that covers the entire pump, including the bladder.

The Sample Pro XD Portable Pump is the first pump developed specifically to bring the advantages of low-flow sampling to sites requiring portable pumps. Pneumatic design can be operated with compressed air or compressed gas cylinder for complete portability.

The Snap Sampler dedicated passive sampling system is the easiest way to collect samples for VOCs, SVOCs, PFAS metals and more. The Snap Sampler system has several advantages over other passive and no-purge sampling devices. Unlike passive diffusion bags that are limited to sampling for a small set of volatile organic compounds (VOCs), the Snap Sampler system collects a whole water sample that can be analyzed for any parameter – VOCs, SVOCs, metals other inorganic parameters, pesticides and nutrients. The sample accuracy and precision surpasses that of no-purge sampling devices that can cause low VOC recovery and suffer from elevated sample turbidity that can bias sample results.

The MicroPurge basicsTM MP10 Controller revolutionizes low-flow sampling with advanced logic control of purge flow and well drawdown. Simple up-down arrow keys increase and decrease purge flow, driving a microprocessor to re-create expert techniques for low-flow adjustment. Then, optimized settings are identified for recall in the next round of sampling. The MP10 also offers an easy way to prevent excessive monitoring well drawdown during purging, by linking to the optional MP30 Draw down/Water Level Meter.

QED PurgeScan Technology provides an easier and more accurate assurance of purge stabilization, automatically signaling when stabilization has been achieved for selected water quality parameters and saving your data file with stabilization noted. MicroPurge MP25 Flow Cell purge water quality monitor leads the field in performance, convenience, completeness and warranty.
