The Watson-Marlow 120S/DM2 and 120U/DM2 pumps comprise a 400DM2 twin-channel pumphead powered by a 120 variable speed or automatic drive. The pumphead accepts 0.8mm wall, three-bridge manifold tubing in sizes from 0.13 to 2.79mm internal diameter. The pump gives flow rates up to 36 ml/min.
120 pumps have a compact footprint, saving valuable space in cleanroom, LAF and biosafety cabinet installations.
120U: 0.1-100 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.
120S: Manual control, 1-100 rpm in 1 rpm increments. Speed scrolling, priming and keypad lock.
Flow rates 0.0001 to 36 ml/min at 2 bar (30 psi).
Compact footprint requires minimal benchtop space
Superior speed control up to 1,000:1, ±1% set speed accuracy, repeatable flow
400DM2 two channel pumphead accepts three-bridge manifold tubing only
Efficient and intuitive to use, requiring minimal key presses
Smooth, wipedown case with no sharp edges to tear gloves and no bug traps. IP31 ingress protection
Maintenance-free, brushless DC motor
Three year warranty
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 new 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 1,000:1 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.
