Back-pressure regulator

Back-pressure regulator 90-300 bar, 1/16“ Connections, stainless steel

Pressure decrease after the column can lead to formation of air bubbles in the detector flow cell resulting in baseline noise and drift. The backpressure regulator provides a quick and convenient way to improve the stability of detector baseline by providing a constant back-pressure on the flow cell, which stops the release of dissolved gases from the mobile phase. The backpressure regulator is made of stainless steel with a low dead volume. A spring-loaded diaphragm provides the force that generates the back-pressure. Spring tension may be adjusted to vary the back-pressure without disconnecting any lines. The pressure is adjustable between 90-300 bar with pessure resistance up to 300 bar.
