After a complex 18-month development programme, DP Seals has delivered its first batch of critical components for the latest sensors designed at the National Oceanography Centre in Southampton.

The microfluidic sensors are among the smallest in situ oceanographic chemical sensors ever made and are to be deployed on a range of oceanographic platforms capable of operating at depths of several thousand metres.

For DP Seals, that meant designing a seal for the sensor’s seawater sampling system that would meet the most stringent standards of performance and reliability in an environment where high pressures, fluctuating chemical properties and very low temperatures would be an everyday reality.

The solution was a bonded rubber seal made from FFKM perfluoroelastomer – a material in which the company has unrivalled expertise – and with the initial order successfully fulfilled, DP Seals is now developing similar components for other applications.

“It’s the first time we’ve worked with DP Seals,” said NOC’s Kevin Saw, “and we were hugely impressed by their complete understanding of our requirements and their ability to meet our brief so effectively.”

DP Seals is a global supplier of high precision custom seals, gaskets and mouldings that play a key role in a huge variety of industrial and commercial applications. They employ over 50 people at their two Poole sites.
