Watson Marlow Pumps Group introduces 120 peristaltic pump


Suitable for single-use systems where contamination is unacceptable

Watson-Marlow Pumps Group's 120 cased peristaltic pumps are suitable for single-use systems where no contamination can be accepted. They have been developed to increase the low-flow capabilities of the company's product range for applications in the biopharmaceutical sector, where customers want a small and simple solution. Watson-Marlow's pump is therefore focused on size, performance and ease-of-use.

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 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.

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 that is vital to drug trials.

Pump size was a priority on the 120 enclosure design because benchtop space is a premium for biopharmaceutical companies. The pumps measure just 110mm in width, which is significantly smaller than most pumps offering similar flow rates. They also benefit from an intuitive interface which makes them quick and simple to set-up and reduces the number of key presses and potential errors.

Simplicity is also captured by the new 114 pumphead, where the spring-loaded flip-top track secures repetitive flow and pressure performance. The 114 pumphead provides error-free tube changing in only seconds, with tubing clamped and tensioned automatically to ensure repeatable performance.

The unit also has a hygienic enclosure suited to ethanol wipe-down, while the smooth lines of the enclosure eliminate bug traps and help prevent the tearing of gloves.

The illuminated numeric speed display provides easy recording of operating parameters, giving customers greater flexibility and repeatability in their processes. A keypad lock prevents accidental key presses, offering process security. All 120 pumps are IP31 rated and carry a three-year warranty.

Processes are boosted further through the use of Watson-Marlow's high tolerance tubing, which is designed specifically to give optimum performance in its pumps.

Further benefiting the bottom line, operating costs can be predicted for the customer over the lifetime of the pump because tubing is the only consumable.
