Back Pressure Regulator
Thar´s Back Pressure Regulator (BPR) is state–of–the–art in back pressure control for supercritical fluids. The back pressure regulator consists of a motor–driven heated valve assembly controlled by a microcontroller. The heated valve assembly compensates for cooling that occurs during depressurization and eliminates plugging. The high–strength stainless steel needle and reinforced PEEK seat have a high resistance to erosion and allow stable pressure control over a wide pressure range. A built–in pressure sensor provides closed loop feedback for pressure control. The back pressure regulator can easily be programmed using a hand held controller for stand–alone operation, or by using an RS232 port with software for advanced control features.
