Details
The Watson-Marlow 120U/R, 120S/R and 120F/R comprise a 102R quick-change pumphead powered by a 120 fixed speed, variable speed or automatic drive. The pumphead accepts 1.6mm wall thickness silicone tubing in sizes from 0.5 to 4.8mm internal diameter. The pump gives flow rates up to 54 ml/min.
120 pumps are small and stackable, saving valuable space in cleanroom, LAF and biosafety cabinet installations.
120U: 0.1-32 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, 1-32 rpm in 1 rpm increments. Speed scrolling, priming and keypad lock.
120F: available in three fixed flow rate versions: 10, 17 and 31rpm.
- Flow rates 0.001 to 54 ml/min at 30 psi (2 bar)
- Compact footprint requires minimal benchtop space
- Superior speed control up to 320:1, ±1% set speed accuracy, repeatable flow
- Efficient and intuitive to use, requiring minimal key presses
- 102R single-channel pumphead accepts continuous silicone 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 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 320:1 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.
