Keyto PEI Diffusion Bonded Manifold

Keyto PEI Diffusion Bonded Manifold | Space-Saving Routing | Custom Port Layout

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 | Space-Saving Routing

Multi-level, multi-path routing designed for space-constrained instruments.

The Keyto PEI-2 diffusion bonded manifold is engineered for dense fluid routing where space, assembly time, and reliability matter. Multi-layer PEI components are diffusion bonded to create compact, sealed networks that support complex functions—from sample dosing and dilution to mixing, reaction routing, separation, and detection. Channel geometry can be selected to fit your performance goals (square, round, or D-shaped), helping you manage dead volume and flow resistance. Share your drawings to tailor port layout, channel structure, and integration interfaces.

FAQ

Q1: What makes PEI-2 different from a standard manifold block?
A: PEI-2 leverages multi-layer bonded routing to achieve complex internal paths that are difficult to realize with single-block drilling.

Q2: Can you help reduce reagent consumption?
A: Yes. Optimized channel volume and minimized dead spaces can reduce hold-up volume and reagent waste.

Q3: Are the channels limited to one shape?
A: No. Square, round, and D-shaped channels are available to match your flow requirements.

Q4: Can you support prototypes and later scale-up?
A: Yes. We can support iterative prototyping and transition to scalable production based on final design stability.
