Idex Ultra Low Volume Back Pressure Regulators

Ultra-Low Volume Back Pressure Regulators (BPR)

• Wetted flow path materials: PEEK™, perfluoroelastomer, and ETFE
• Available pressure settings of 100 or 500 psi (7 or 34 bar)
• Low swept volume of only 6 μL
• Ultra-Low Volume Back Pressure Regulators

(BPRs) were developed to minimize swept volume, which is especially important for multi-detector applications. With a maximum swept volume of only 6 μL*, it is nearly impossible to detect these BPRs as part of your fluid pathway (please see “Difficult to Detect” below for more details). To minimize the swept volume added to your flow path, we recommend trimming the length of the attached tubing. And because the flow path is completely polymeric, you are assured of biocompatibility.

Please Note: Our Ultra-Low Volume Back Pressure Regulators cannot be used as check valves due to their unique internal design. Try our Micro-Volume Inline Check Valve. 

* The maximum internal swept volume listed above is for the back pressure regulator only and does not include the volume of the attached tubing lines.
