Be Sure. Go Custom.

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.

Wash, Rinse, Repeat Engineering Need Not Apply

Wash, rinse, repeat – once found only on shampoo bottles – has moved into the everyday American lexicon. Now it’s commonly used as a humorous way of saying that instructions should be repeated until a certain goal is reached.

That may be so in everyday life, but that’s no way to engineer a solution for solving any customer’s fluidic challenge.

New assays are being developed that are far more sensitive than the current ones in the market today, enabling test results with ever increasing accuracy. In order to run these new assays on existing or new instruments, OEMs need to reduce sample carryover significantly. The difficulty with doing that in existing instruments is that modifications must be easy to install and fit inside the current machine envelope.

The Need:
One of our global OEM customers asked for Diba’s help designing a retrofit heater for an existing instrument that improved its performance.

The Customer Challenge:
This OEM needed to precisely heat a critical fluid in their existing instrument. Existing instruments pose particular challenges of their own: namely, that any modifications made have to be easy to install and fit inside the current machine envelope.

The Solution:
Our solution involved designing a compact and powerful heater that heated a critical fluid and a custom manifold to handle fluid transfer and mixing.
