The Watson-Marlow 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

Superior speed control up to 2,000:1, ±1% set speed accuracy, repeatable flow

114DV single-channel, flip-top pumphead accepts continuous 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 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.
