According to a new application note, Thermo Scientific Masterflex pumps provide precise, seamless liquid filling.
Maintaining precise dosing accuracy with high repeatability presents challenges for liquid fillers - especially when operating centrifugal or rotary lobe pumps for lower-volume products such as vials, single doses and injectables.
Precision liquid filling is said to be vital for product integrity, and high repeatability ensures that production schedules can be precisely set and met.
It is often difficult to pump ultra-precise flow rates with rotary lobe pumps, however.
In addition, like centrifugal pumps, they are often time consuming to clean and sterilise.
Masterflex peristaltic pumps are claimed to be particularly suitable for pharmaceutical liquid-filling applications, from bench-top fillers to large-scale automatic systems.
Thermo Scientific Masterflex pumps maintain a precise, constant flow rate with excellent repeatability, providing volumetric accuracies of +/-0.5 per cent of liquid fill volume or better.
Customers also gain speed and flexibility because product comes into contact with only the tubing and filling needle, which can be replaced in less than a minute.
