Watson-Marlow 120 Series Benchtop Pumps with 400D1 single channel pumphead

The Watson-Marlow 120S/D1 and 120U/D1 pumps comprise a 400D1 single channel pumphead powered by a 120 variable speed or automatic drive. The pumphead accepts 1.6 mm wall, continuous tubing in five materials in sizes from 0.5 to 4.0 mm internal diameter. The pump gives flow rates up to 120 ml/min.

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.

120U: 0.1-200 rpm in 0.1 rpm increments. Manual remote control or automatic control via 4-20mA or 0-10V inputs. Speed scrolling, priming and keypad lock.

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 optimise 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.

Process validation The biopharm process requires accurate and repeatable pumping which is easy to validate. With an exceptional 2,000:1 speed range, the 120 delivers the flexibility and purity so vital to drug trials. A keypad lock secures your pumping parameters for constant and repeatable performance.

400D1 single channel pumphead:
