2/2 or 3/2 Way Rocker Valve Type 0127

A microfluidic rocker valve combines low internal volume with minimal dead volume, for less unused fluid and a reduced chance of contamination. A PEEK body, FFKM seal, and separating diaphragm between the fluid and actuator gives maximum chemical resistance, making this valve a cost-effective industry standard for a wide range of laboratory, medical and analysis applications.
Available in 2-way normally closed and 3-way versions.

Maximum precision

In the world of microfluidics, precision and reproducibility are must-haves. Bürkert microvalves have been able to meet these demands through innovative solutions and precise manufacturing standards to provide devices that are both high-performance and long-lasting. With a switching speed of 25 ms, this valve provides fast and reliable operation.

Excellent cleanability

Cross-contamination can be a serious issue in microfluidics, particularly when working with biological media. Thanks to their low dead volume designs, optimised flow paths and precision molding, Bürkert has ensured that their microvalves are easily cleanable. Utilizing a diaphragm to separate the media from the actuation mechanism, this valve maintains this commitment to cleanability.

Low internal volume

When material costs are high, they should be used more efficiently. By minimizing the internal volume of their valves, Burkert not only improves their cleanability, but also facilitates the most efficient use of precious fluid resources. This microvalve has a total internal volume of <70 µL, for applications in which liquid efficiency is key.

Outstanding chemical resistance

Whether you're working with strong acids, concentrated solvents, or cell suspensions, Burkert microvalves are manufactured in close concert with their chemical laboratories to ensure their materials are being used to ensure chemical resistance in the most critical of applications. With a PEEK body and FFKM seal, this valve is second to none in terms of chemical compatibility.

Low heat transfer to the medium

By keeping the actuating solenoid and the fluid chamber separate in their microvalves, Bürkert minimizes the uncontrolled heat transfer into the fluid medium. Additionally, low microvalve power consumption helps reduce heat production.
