Microfluidic On/Off valves are fundamental components in microfluidic systems, designed to precisely control the start and stop of fluid flow within small channels. These valves serve as essential tools in a wide variety of applications, ranging from biological assays to chemical reactions, where precise timing and fluid control are critical for successful outcomes.
In the context of microfluidics, On/Off valves act as gatekeepers, enabling or halting the flow of liquid with remarkable accuracy. These valves are particularly useful in experiments that require rapid, repeatable control over fluid movement, such as sequential sample injections, reagent mixing, or the isolation of specific fluid paths.
The ability to automate the opening and closing of fluidic channels enhances workflow efficiency, reduces the need for manual intervention, and ensures consistency across experiments. Whether applied in pharmaceutical research, diagnostics, or industrial processing, microfluidic On/Off valves are vital for maintaining the integrity and reproducibility of experiments, while also improving operational speed and reducing error rates.
By controlling the flow in a straightforward open/close manner, On/Off valves provide precise and automated control over fluid movement. This enhances workflow efficiency in applications such as sample loading, reagent mixing, and stopping fluid flow in sensitive protocols, ensuring reliable performance across different environments.
An On/Off rotary valve uses a rotating mechanism to control the flow, providing precise control with extremely low internal volume and optimized fluid management.
AMF’s On/Off microfluidic valves are expertly engineered to deliver high performance, reliability, and precision across a wide range of applications.
One of the key features of AMF’s On/Off microfluidic valves is their low internal volume, which can be as low as 3 µL, with even smaller volumes possible through customization. AMF’s valves are designed to minimize internal volume, ensuring precise fluid control and reducing the amount of liquid retained within the system. This feature is particularly advantageous in applications that handle expensive reagents or require precise fluid dosing, as it reduces the amount of fluid wasted and improves the overall efficiency of the system. The low internal volume also helps to enhance response times, allowing for quicker fluid switching and better system performance, making these valves ideal for high-precision workflows.
Dead volume, the trapped fluid that remains in inactive areas of the valve, can cause significant problems in fluidic systems. This residue can lead to contamination, incomplete fluid switching, and incorrect measurements. AMF’s On/Off valves are specifically designed with zero dead volume, ensuring that no residual liquid remains after rinsing, allowing thorough cleaning between uses. This ensures that fluid is fully removed from the system, reducing contamination risks and ensuring the purity of each subsequent liquid in the flow path. This feature is particularly valuable in processes where cross-contamination must be avoided, such as in biological and medical research, where clean, uncontaminated samples are critical to achieving accurate results.
AMF’s On/Off valves are built to last. The materials used in their construction offer strong chemical resistance and reliable mechanical resilience, making them well-suited for the demands of industrial and research environments. Whether used in high-throughput chemical synthesis or long-term biological experiments, AMF’s valves are designed for consistent, repeatable performance. The robust construction also means that these valves require less maintenance, reducing downtime and ensuring continuous operation in fluidic systems.
AMF’s valves are engineered with the highest precision standards, ensuring reliable and accurate control over fluid flow. The precision machining of the valve components, combined with stringent quality control processes, guarantees that each valve operates with minimal deviation, delivering consistent results over time.
One of the significant advantages of AMF’s On/Off microfluidic valves is their ability to replace traditional solenoid valves, particularly in applications where volume displacement can have important impact. Unlike solenoid valves, which rely on bulky mechanisms that can displace higher fluid volumes and introduce inaccuracies, AMF’s On/Off valves operate with minimal internal volume and no dead volume. This ensures that only the exact required amount of fluid is moved through the system, avoiding unintended fluid displacement that can affect process accuracy. By reducing the volume displaced during operation, AMF’s valves deliver better control over small-volume applications, making them ideal for high-precision workflows where accuracy and efficiency are paramount.
AMF’s On/Off valves are available in several configurations, with detailed specifications that meet the demands of various industries. To better understand our component references, here is a breakdown of the nomenclature used for our valves:
V-A-B-C-D-E-F (e.g. V-D-1-5-050-C-P)
Below are examples of configurations and key performance parameters, such as internal volume, carryover volume, fluid path diameter, and maximum pressure handling.
AMF’s On/Off valves are specifically designed for seamless integration with the RVM Industrial Microfluidic Rotary Valve. This compatibility ensures precise fluid control and easy incorporation into existing fluidic systems that utilize the RVM. By working exclusively with the RVM, these On/Off valves provide enhanced fluid handling efficiency, allowing users to optimize workflows with reliable, high-precision switching. This dedicated integration minimizes complexity and maximizes performance in demanding applications.
Moreover, the integration of AMF’s On/Off valves with the RVM simplifies the overall system architecture. Since the RVM can manage multiple fluid pathways while incorporating the On/Off valves for complete control, users benefit from an all-in-one solution for fluid routing and switching. This reduces the need for additional components and minimizes potential points of failure. As a result, the RVM withAMF’s On/Off valves creates a highly efficient, compact system that is ideal for complex fluidic setups, ensuring optimal performance and operational simplicity.
