Ultimately the 120 pumps have been developed to increase the low-flow capabilities of the company’s product range for applications in the biopharm sector. The market need for the 120 range is well understood, with customers voicing their own mantra, "keep it small, keep it simple". As a result, Watson-Marlow has produced a pump that is focussed on size, performance and ease-of-use.

Eric W. Johnson at Novozymes Inc, who was one of the first people to use the new 120 pump comments: "I love simple and this has a small footprint without a lot of bells and whistles. Easy menu, short learning curve, improved performance, and hopefully zero maintenance, have generally left me very impressed and satisfied with this unit."

The biopharm sector embraces applications such as fermenter feed, an upstream process important in both production and research, where the growth of cell cultures demands an accurate and repeatable process with no contamination. Ultra-compact and stackable for multiple feeds like pH control, antifoam, nutrient and buffer addition, the 120 offers the ideal combination of size and technology to optimise the process. The pump will also be effective where the validation of drug research experiments demands accurate flow rate, easy monitoring of parameters and process control.

Biopharm processes require accurate and repeatable pumping that is easy to validate. With an exceptional 2,000:1 speed range (speed accuracy ±1%) and a selection of USP Class VI tubes, the 120 delivers the flexibility and purity so vital to drug trials.
