Design engineers who are tasked with optimizing fluidic flow path performance have important decisions to make when designing for medical, life sciences or diagnostic applications.
Traditional fluidic component options that are available for design engineers may consist of off-the-shelf thermoplastic machined manifolds, standard fittings, tubing assemblies, valves, pumps and filters.
Design engineers must not only select the components to meet their application requirements, they must also consider how the integration of the components are managed for new system production and for serviceability of the system after it has been released to the market.
There is a real benefit for design engineers to explore the use of a custom-designed and thermally bonded fluidic manifold assemblies to achieve their goal of optimizing fluid paths while also providing a serviceable solution that will allow easy access to fluidic interfaces and components.
For example, a custom ULTEM- or PMMA-bonded manifold assembly can perform as the system’s ‘Fluidic Hub’ for virtually all critical fluidic system interfaces. A well-designed manifold assembly will include direct connection points for valves, pumps, regulators and sensors used for fluid control and measurement. As the total number of connection points is reduced, space and weight considerations can be also reduced – typically by 50% or more using this design approach.
On the other hand, the use of standard off-the-shelf components will often result in system design limitations and other undesirable fluidic-related characteristics, such as additional connection points, excess dead volume and potential sample carry-over contamination.
For design engineers working on next generation medical or diagnostics applications, partnering with a company that has expertise in the design and manufacture of thermally-bonded manifold assemblies is an important step in the right direction. This approach will help them ensure their project goals of optimized performance and superb field serviceability are achieved.
