The MP15 MicroPurge Backpack combines advanced low-flow control with a built-in compressed gas source's quiet power for ultimate portability and ease of use in sampling groundwater with bladder pumps.

The MicroPurge MP15 Controller revolutionizes low-flow groundwater 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.
Portable power to sample groundwater with any bladder pump

The easy, advanced MicroPurge flow rate and drawdown control features are housed in a molded case and a lightweight CO2 cylinder, putting everything you need to operate bladder pumps into one easily portable unit. A standard padded nylon case protects the MP15 MicroPurge control & power pack in transport, provides over-the-shoulder on-site carrying convenience, and even has a hook on the back to let you hang it from the well casing during sampling.

With this combination, a single person can carry a complete sampling setup to reach wells where trucks or even compressor carts can't go.
