Overview
EN ISO 22916:2022 - Microfluidic devices: Interoperability requirements for dimensions, connections and initial device classification - specifies minimum interface requirements to enable seamless integration of microfluidic components (chips, sensors, actuators, connectors). Adopted by CEN as EN ISO 22916:2022, this standard targets interoperability in the microfluidics ecosystem so devices from different suppliers can be connected, tested and deployed with reduced custom engineering effort.
Key topics
- Scope and applicability: Requirements for devices in the field of microfluidics that require microfluidic interconnections.
- Reference and terminology: Uses ISO 10991 vocabulary for consistent definitions.
- Chip topology and reference point: Guidance on chip layout, naming and a defined reference point to enable repeatable positioning and interfacing.
- Dimensional requirements: General tolerances plus specific guidance for chip thickness and outer dimensions aligned to common formats (microplate compatibility, microscope slide format, credit-card-like formats).
- Building blocks: Standardized microfluidic building-block concepts to simplify design reuse and modularity.
- Top and side connections: Specifications for port pitch, port diameter/shape, distances from edges, port nomenclature, interfacing areas and clamping zones to ensure reliable mechanical and fluidic connections.
- Application classes: Initial device classification with temperature and pressure boundary conditions that inform standardized testing (e.g., leakage, burst pressure, flow throughput) and product readiness.
Applications and users
EN ISO 22916:2022 is practical for:
- Device designers and OEMs creating microfluidic chips, cartridges and connectors - to design components that plug into existing systems.
- System integrators and instrument manufacturers who need predictable interfaces for pumps, sensors and peripheral modules.
- Research labs and academia seeking to swap or combine chips from multiple sources without redesigning fixtures.
- Test laboratories and quality teams using the application-class boundaries to develop cross‑technology tests and validation protocols.
- Regulatory and procurement teams evaluating interoperability and second‑source availability.
Adoption of this standard reduces custom tooling, accelerates prototyping, and simplifies scale-up and manufacturing transitions.
