Watson-Marlow has introduced the 120 cased peristaltic pumps, developed to increase the low-flow capabilities of the company’s product range for applications in the biopharm sector.

The biopharm sector includes 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 such as pH control, antifoam, nutrient and buffer addition, the 120 offers a suitable 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 a 2,000:1 speed range (speed accuracy +/-1 per cent) and a selection of USP Class IV tubes, the 120 delivers the flexibility and purity vital to drug trials.

Watson-Marlow said pump size was a priority on the 120 enclosure design because bench-top space is a premium for biopharm companies.

Pumps measure 110mm in width, which is smaller than most pumps offering similar flow rates, the company added.

The 120 pumps also benefit from an intuitive interface that makes them quick and simple to set up and reduces the number of key presses and potential errors.

The spring-loaded flip-top track of the 114 pumphead secures repetitive flow and pressure performance.

The 114 pumphead provides error-free tube changing in seconds, with tubing clamped and tensioned automatically to ensure repeatable performance.

The IP31-rated 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.

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

Operating costs can be predicted for the customer over the lifetime of the pump because tubing is the only consumable.

The ultra-quiet 120 cased pump range is available with three different models for fixed speed, manual or remote auto control, and five single- and multi-channel pumpheads.

All 120 pumps are IP31 rated and carry a three-year warranty.
