These ultra-low volume back pressure regulators (BPRs) are developed to minimise swept volume, which is especially important for multi-detector applications.

• Completely polymeric flow path, assuring biocompatibility

With a maximum swept volume of only 6 μl, it is nearly impossible to detect these BPRs as part of the fluid pathway. To minimise the swept volume added to the flow path, it is recommended to trim the length of the attached tubing.
