Teledyne Isco’s Model 4700 Refrigerated Samplers set new standards for weather and corrosion resistance. They feature a tough, rotationally-molded, fully-insulated cabinet; an energy-efficient, high-performance compressor; polyester powder coating to protect the entire refrigeration system against corrosion; and a sealed, NEMA 4X, 6 (IP67) electronics enclosure. The company’s patented liquid detector and pump counting system ensure sample volume accuracy and repeatability.
