Precision Milled Pathways in a Diffusion Bonded Acrylic Manifold for Use in In Vitro Diagnostics

What is Diffusion Bonding?

Multiple layers of plastic are molecularly fused to create a 3 dimensional microfluidic circuit. In concept, similar to an electronic circuit board, diffusion bonded manifolds concentrate fluid paths into a limited space requirement.

Advantages

Optically Clear
Complex Features
Precise Tolerances
Ease of Assembly
Lower Maintenance
Visible Flow Paths
Volume Reduction
Burr free intersections

Common Materials

Acrylic (PMMA)
Ultem (Polyetherimide)
Polycarbonate (PC)

Diffusion Bonded Ultem Manifolds

Diffusion bonded Ultem (Polyetherimide or PEI) manifolds provide the flexibility of design that makes fluidic manifolds so appealing. Bonded Ultem (Polyetherimide) also provides excellent thermal, chemical, and physical properties that allow it to be used in the most demanding, harsh environments and applications.

Machined Plastic Manifolds

This cost effective solution integrates a fluidic flow path with straight machined features. The absence of bonding allows for the use of a large variety of engineered plastic materials.
