Watson-Marlow's Pumpsil-D Brings Accurate and Precise Dispensing Tubing to the Market
27 April 2006
Driven by increased demand for accurate dispensing, Watson-Marlow, a leader in peristaltic technology, has developed Pumpsil-D, a revolutionary new platinum-cured silicone tubing offering unrivalled dispensing accuracy and precision. The tubing is already being widely used within the pharmaceutical industry.
The nature of the tube offers superior resistance to fatigue stress and improved restitution after compression during the pumping action. For example, the restitution in a normal platinum-cured silicone tube deteriorates at a much higher rate over a period of time compared to Pumpsil-D which is incredibly resistant to permanent deterioration, delivering accurate and precise dispensing.
Pumpsil-D is a unique material developed through careful selection of raw materials, close monitoring of the extrusion process and post-curing of the extruded tubing. The post-curing process allows cross-linking between the silicone molecules, resulting in tighter bonds, which maximise resistance to flexing stress.
Martin Johnston, Product Manager, Watson-Marlow said: "Pumpsil-D is the result of over two years' research and development, including a six-month testing period of trialling the product both internally and at customer sites. Over 80% of customers involved in the trial are now using it as a selected product in their facilities.
In addition to the improvements in accuracy, Pumpsil-D also offers an ultra-smooth bore, helping to reduce protein binding and bacterial growth, making it ideal for clean, accurate environments."
Watson-Marlow is a leader in peristaltic technology, supplying pumps for a range of environments from the pharmaceutical industry to heavy industrial plants. The company has invested heavily in a £1.4 million tubing extrusion plant which offers a state of the art Class J10,000 clean room based at its Falmouth site, Cornwall.
