MASTERFLEX E/S PORTABLE SAMPLER
This pumping system mates the newest Masterflex portable sampling drive with a Quick Load pump head, for a powerful but versatile unit that takes to the field like a duck to water. The pump head accepts L/S 13, 14, 16 or 25 tubing, and tubing changes in the field can be made in a matter of minutes without having to remove the pump head from the drive. The stainless steel rotor offers across-the-board chemical resistance. A one-turn potentiometer controls pump speed, or the MAX switch immediately takes the pump to maximum speed. Purging and sampling are accomplished with a rotational direction switch that selects forward or reversible flow. The entire drive and head assembly are housed in a highly visible protective enclosure.
