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.

  • Flow rates 0.001 to 120 ml/min at  30 psi (2 bar)
  • Compact footprint requires minimal benchtop space
  • Superior speed control up to 2,000:1, ±1% set speed accuracy, repeatable flow
  • Efficient and intuitive to use, requiring minimal key presses
  • 400D1 single-channel pumphead accepts continuous tubing only
  • 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 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.

Pumphead

400D1 single channel pumphead:

The single channel 400D1 pumphead accepts 1.6mm wall tubing from 0.5mm to 4.0mm. This metering pumphead is familiar to users replacing older 101 and 400 series pumps with the 120. Suitable for 120S and 120U drives.

114DV flip-top four roller pumphead

 The 114DV single-channel pumphead assures trouble-free continuous tube loading in seconds, high accuracy and repeatable flow. It accepts 1.6mm wall tubing in bores sizes 0.5mm to 4.8mm.

 

102R single-channel two roller pumphead

 The 102R single-channel pumphead with two-roller rotor is suitable for continuous silicone tubing. It accepts tubing in bore sizes 0.5mm to 4.8mm.

 

400DM2 twin-channel pumphead

 The twin-channel 400DM2 pumphead uses three-bridge manifold tubing. Ideal for ultra-low-flow metering. Available for 120S and 120U drives.

 

400DM3 three-channel pumphead

 The three-channel 400DM3 pumphead uses three-bridge manifold tubing. Ideal for ultra-low-flow metering. Available for 120S and 120U drives.
