Keyto PEI Diffusion Bonded Manifold | Flow Resistance Optimization

Keyto PEI Diffusion Bonded Manifold | Flow Resistance Optimization | Reagent Saving

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 | Flow Resistance Optimization | Reagent Saving

Production-oriented customization for stable designs and scalable manufacturing.

Keyto’s PEI-7 diffusion bonded manifold is developed for projects that need a clear path from custom design to scalable production. The multi-layer diffusion bonded structure forms sealed internal channels with controlled geometry and compact routing density, supporting up to five layers for complex layouts. Channel shapes (square, round, D-shaped) can be selected to match performance targets, and minimum channel features can reach 0.5 mm with ±0.01 mm tolerance (design dependent). PEI-7 consolidates multiple fluid steps—sampling, dilution, mixing, reaction routing, separation, and detection—into a single module to simplify assembly and improve reliability.

FAQ

Q1: Can PEI-7 support scale-up after prototyping?
A: Yes. PEI-7 is positioned for projects moving from validation to repeatable manufacturing.

Q2: What bonding technologies are available if diffusion bonding isn’t ideal?
A: We can also apply solvent bonding, laser bonding, or ultrasonic bonding depending on material and design constraints.

Q3: Can you accommodate custom port standards?
A: Yes. Port types and positions can be customized to match your connectors, tubing, or device interfaces.

Q4: How do you ensure design consistency across batches?
A: Consistency is achieved through controlled channel geometry, manufacturability review, and validation aligned with your requirements.
