Keyto PEI Diffusion Bonded Manifold | Integrated Workflow Manifold

Keyto's bonded manifold is made by molecular bonding of multi-layer processed parts with specific flow path features and supports up to five layers. It integrates functions such as sample addition, dilution, reagent mixing, reaction, separation, and detection, saving reagents and enhancing system integration. The manifold supports multi-level, multi-fluid path designs with material options including PMMA, PEI, and PVC, and offers O-type, square, and D-type flow path structures. Keyto's O-type structure provides large fluidity, low resistance, and minimal dead volume, supported by mature mass production capabilities.

Overview

Keyto PEI Diffusion Bonded Manifold | Integrated Workflow Manifold

Workflow integration manifold: combine multiple fluid steps into one compact module.

The Keyto PEI-4 diffusion bonded manifold is designed around workflow consolidation—bringing multiple liquid-handling steps into a single, compact fluidic module. By diffusion bonding layered PEI structures, PEI-4 enables integrated functions such as sample introduction, dilution, reagent mixing, reaction routing, separation, and detection, while reducing external connections and assembly complexity. The manifold supports up to five layers and offers configurable channel geometries (square, round, D-shaped) to tune dead volume and flow resistance. Send your 2D/3D drawings to customize port interfaces, routing complexity, and integration readiness.

FAQ

Q1: What workflows can PEI-4 support?
A: Typical workflows include sampling, dilution, mixing, reaction handling, separation routing, and detection flow paths—configurable per design.

Q2: Can you design manifolds for specific instruments?
A: Yes. We tailor channel layout, port positions, and interfaces to match your instrument architecture.

Q3: Does a bonded manifold reduce assembly time?
A: In many systems, yes—because multiple tubing and connector steps are consolidated into one module.

Q4: How do I start a custom request?
A: Share your CAD and key operating conditions (media, temperature, pressure, flow targets). We’ll propose a manufacturable solution.
