Why compact integration matters
In modern OEM instruments, fluidic performance is often limited not by chemistry or mechanics, but by how components are integrated. As systems become smaller and more complex, integration challenges quickly impact footprint, reliability, and development time.
- Limited space inside compact instruments
- External controllers increase wiring and complexity
- Multiple interfaces increase integration risk
A more integrated approach to fluid routing enables simpler architectures, faster development, and more reliable systems.

Available in configurations from 2 to 12 ports, the valve supports flexible routing for multi-channel and automated fluid handling applications.
The valve head combines PCTFE and PTFE for broad chemical compatibility, with additional materials such as PEEK, UHMW-PE or full PTFE available for specific requirements. It integrates a new-generation electric motor and supports multiple communication interfaces, ensuring seamless integration into OEM systems. Designed as a robust microfluidic component, it can be easily integrated with tubing, pumps, sensors, and OEM control environments while remaining adaptable to industrial manufacturing constraints.

Simplifying OEM system integration
Traditional fluidic systems often rely on distributed architectures with separate motors, driver boards, connectors, and wiring harnesses. As systems become more compact and multi-channel, this approach increases integration complexity, footprint, and potential failure points.
The RVM mini addresses these challenges by embedding motion control and communication electronics directly into the rotary valve. Multiple communication interfaces, including USB-C, RS232, RS485, TTL, analog I/O, and I2C with power, are integrated into a single compact component, enabling simplified electrical and mechanical integration into OEM systems.
This architecture reduces external components while improving robustness, scalability, and ease of integration in automated microfluidic instruments.

Designed for compact OEM systems
Fully integrated
The rotary valve integrates the motor, drive electronics, and PCB directly into a single compact body. There is no external controller, no additional wiring harness, and no separate mounting for electronics. This reduces system complexity, shortens integration time, and limits potential failure points. For OEM developers, this means a cleaner architecture, easier validation, and faster transition from prototype to series production. Everything required to operate the valve is already embedded, enabling direct integration into space-constrained instruments without compromising control or performance.
Minimal footprint
Designed to fit where standard rotary valves cannot, this valve dramatically reduces the occupied volume inside an instrument. Its compact footprint frees up space for additional functions, shorter fluid paths, or smaller enclosures. By minimizing the space required for both the valve and its control hardware, OEMs can simplify mechanical design, reduce routing constraints, and design more compact systems. This is especially valuable in benchtop, portable, or multi-module instruments where every cubic centimeter matters.

New possibilities for compact fluidic architectures
A compact routing solution for multi-layer systems
The RVM mini is not only designed to be smaller. It enables new microfluidic architectures by simplifying how fluidic layers and functional zones are connected inside an instrument.
In complex OEM systems, routing fluids between different functional areas often requires multiple tubes, connectors, and external valves. This increases footprint, internal volumes, and integration complexity. In this application example, the RVM mini is integrated into a two-layer fluidic manifold combining solenoid valves and reaction chambers within a compact, structured block.
- Layer 1 hosts a first functional zone with a dedicated reaction chamber
- Layer 2 hosts a second functional zone with its own reaction chamber
- Integrated solenoid valves control inlets, outlets, waste, and wash lines
The challenge is to route fluids cleanly between these two layers without adding tubing bridges or unnecessary dead volume.
The role of the RVM mini
The RVM mini acts as a compact microfluidic router inside the manifold. Using a 3D rotary valve function, it directly interfaces layer 1 and layer 2 within the same integrated structure.
Instead of connecting layers with external tubing, the rotary valve provides a clean, internal transition between functional zones. All fluids pass through a single, controlled routing path, which can be fully flushed during wash steps. This simplifies cleaning and helps maintain consistent fluidic conditions over time.
By routing samples and reagents through the rotary valve, solenoid valves are only used for line selection and isolation. Reactive fluids do not pass through the solenoids, reducing contamination risk and extending component lifetime.
This architecture also enables random access operation. Each functional zone can be addressed independently, allowing the system to process samples as they arrive rather than following a fixed, fully sequential cycle.
Clean routing, full washability, and independent zone access are key to building compact, reliable, and flexible microfluidic instruments.
Inside the routing concept
The RVM mini is designed to do more than switch lines. Its internal rotary architecture enables controlled routing between multiple fluidic layers within a compact, integrated structure.
By embedding routing inside the valve itself, complex fluidic connections are handled internally. This reduces external tubing, simplifies integration, and enables compact multilayer designs without exposing sensitive routing to the rest of the system.
From sequential to parallelized operations
In many fluidic instruments, operations are performed sequentially, not because it is optimal, but because routing and zone independence are limited.
By combining a multilayer manifold with the RVM mini, fluidic operations can be reorganized to reduce idle time and improve overall efficiency and this enables:
Optimized footprint
Independent functional zones are enabled within a compact, multilayer manifold. Parallel operation is achieved without adding components or increasing the instrument footprint.
Multi-layer architecture
Multiple functional layers can be connected cleanly within the same fluidic block. Routing between layers is internal, controlled, and does not rely on external tubing.
Washable fluidic paths
All critical fluid routing passes through a single, controlled path that can be fully flushed. This simplifies cleaning, limits carryover, and supports reliable long-term operation.
Multiplexing and random access
Each zone can be addressed independently. Samples or reagents can be routed as needed, enabling multiplexing and random access workflows instead of fixed sequential cycles.
Better handling of sensitive samples
Optimized internal volumes, reduced dead volume, and fewer interfaces help protect valuable or sensitive samples from loss and contamination.
Improved system utilization
When one zone is incubating or waiting, the other can continue operating. Idle time is reduced and overall system efficiency improves without added complexity.
The visual comparison above highlights how clean routing and zone independence transform system performance.
What this changes at system level
By enabling cleaner routing and more independent functional zones, the RVM mini changes how microfluidic systems can be designed and operated.
The impact goes beyond fluid control and affects overall instrument performance, scalability, and robustness.
Shorter time per sample
Parallelized operations reduce idle phases during incubation and washing, shortening the overall processing time.
Higher throughput or more compact instruments
OEMs can increase throughput within the same footprint, or maintain performance while reducing instrument size and complexity.
Random access capability
Systems can process samples arriving at different times without waiting for a full batch cycle to complete.
Simpler and more robust architectures
Fewer tubes, connectors, and interfaces mean fewer leak points, easier assembly, and improved long-term reliability.
