Back pressure regulators
Supplier: Restek
Backpressure regulators can improve detector performance by preventing bubble formation in the detector flow cell. They also are useful in post-column reaction lines and between detectors and fraction collectors in preparatory work. Regulators are superior to more specific alternative solutions like small bore tubing, in which pressure varies with flow rate.
