Watson-Marlow 120S/DM2 Peristaltic Pump
The Watson-Marlow 120S pump is comprised of a twin channel pump head 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 120S offers 1-100 rpm operation in 1 rpm increments. It features speed scrolling, priming and keypad lock.
Fermentation
The 120S 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 120S 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.
Intuitive use
An intuitive interface makes the pump easy and quick to set up, with fewer key presses for fewer mistakes, bringing maximum efficiency to your process.
Compact footprint
The compact, stackable 120 pump saves valuable space in cleanroom, LAF and biosafety cabinet installations.
