Keyto PEI Diffusion Bonded Manifold | Up to 5 Layers

Keyto PEI Diffusion Bonded Manifold | Up to 5 Layers | Compact Multi-Path

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

High-integration PEI manifold for compact systems and repeatable fluid control.

Keyto’s PEI diffusion bonded manifold integrates multi-level, multi-fluid-path routing into a single compact module, reducing external tubing, fittings, and potential leak points. By bonding precision-processed PEI layers at the molecular level, the manifold delivers stable flow routing for sample addition, dilution, reagent mixing, reaction handling, separation, and detection. The design supports up to five layers and can be configured with square, round, or D-shaped channels to meet specific resistance and dead-volume targets.

FAQ

Q1: Why PEI (Ultem) for diffusion bonded manifolds?
A: PEI is typically selected for applications requiring stronger mechanical performance and stable structure in compact assemblies.

Q2: Can you build multi-level routing in one manifold?
A: Yes. Multi-level routing is a key advantage of bonded manifolds and helps simplify complex liquid-handling systems.

Q3: Do you provide DFM suggestions?
A: Yes. We provide channel/layout feedback to improve manufacturability, sealing reliability, and performance consistency.

Q4: Can this manifold be used as a base for system integration?
A: Yes. PEI manifolds are often used as a fluidic base for integrating valves, pumps, and connectors in a higher-level assembly.
