Our Low Flow Micro-Volume BPR Assembly was developed to specifically minimize swept volume which is extremely important for multi-detector applications. Our BPR Assembly has a maximum swept volume of only 6uL making it nearly impossible to detect as part of your fluidic pathway. It is for a 1/16 tubing OD and has a pressure setting of 500psi (34 bar) It comes with (1) P-230 Flangeless Fitting.
