Watson Marlow 100 series laboratory pumps 120U/DV 120S/DV and 120F/DV, comprise a 114DV flip-top pumphead powered by a 120 fixed speed, variable speed or automatic drive. The pumphead accepts 1.6mm wall thickness tubing in a choice of five materials in sizes from 0.5 to 4.8mm internal diameter. The flip-top loading mechanism allows tube loading in seconds. The pumps give flow rates up to 170 ml/min.Compact footprint requires minimal benchtop space.
Main features
120 pumps are small and stackable, saving valuable space in cleanroom, LAF and biosafety cabinet installations

120S: Manual control, 1-200 rpm in 1 rpm increments. Speed scrolling, priming and keypad lock
120F: available in five fixed flow rate versions: 10, 17, 31, 52 and 220 rpm.
Flow rates 0.001 to 170 ml/min at 2 bar (30psi)
Watson Marlow 100 series laboratory pumps
Fermentation: the 120 is the perfect pump for maximising yield in fermentation and cell culture applications. Ultra-compact and stackable for multiple feeds such as pH control, antifoam, nutrient and buffer addition, the 120 offers the ideal combination of size and technology to optimize your process.
Single-use systems: The 120 pump is perfectly suited to single-use systems where no contamination can be accepted. Error-free tube change takes only seconds, with tubing automatically clamped and tensioned to ensure repeatable performance.
Process validation: the biopharm process requires accurate and repeatable pumping which is easy to validate. With an exceptional 2,000:1 speed range and a selection of USP Class VI tubes, the 120 delivers the flexibility and purity so vital to drug trials. A keypad lock secures your pumping parameters for constant and repeatable performance.
