The Sample Pro Portable MicroPurge Pump is the first pump developed specifically to bring the advantages of low-flow sampling to sites where groundwater samples are collected from many monitoring wells with the same pump.

The Sample Pro pump is easy to disassemble, without any tools, and simple to clean to eliminate any potential cross contamination. That includes the exclusive Sample Pro disposable bladder, which snaps in and out without any clamps, so they can be discarded after each well is sampled.  The Sample Pro is capable of pumping from depths up to 200 ft. (61m).
