Watson-Marlow Fluid Technology Group, Wilmington, Mass, has launched its 120 peristaltic pump range, which is suited to single-use systems where no contamination can be accepted. Ultra-compact and stackable for multiple feeds like pH control, antifoam, nutrient, and buffer addition, the range seeks to optimize workflow processes. Features include an intuitive interface, illuminated numeric speed display, a 2,000:1 speed range (speed accuracy ±1%), a hygienic enclosure, and a selection of USP Class VI tubes. Understanding that benchtop space is at a premium, pumps measure just 110 mm in width, which is significantly smaller than most pumps offering similar flow rates. A new 114 pumphead enables a spring-loaded flip-top track to secure repetitive flow and pressure performance. The pumphead ensures error-free tube changing, with tubing clamped and tensioned automatically to ensure repeatable performance. Available with three different models for fixed speed, manual, or remote auto control, the range comes with five single and multichannel pumpheads. Pumps are IP31 rated and carry a 3-year warranty.
