The In-Line Degasser AF removes dissolved gases from samples, which is a necessary step for obtaining accurate readings in HPLC. It features a zero hysteresis/constant-run vacuum pump with a stepper motor for membrane degassing of HPLC mobile phases

• The continuous running pump cycles between high-speed, to provide rapid vacuum pull-down, and low-speed, to sustain a consistent vacuum level
• This unique approach enables rapid vacuum equilibration for faster eluent equilibration
• The continuous operating mode improves chromatographic performance for high-sensitivity applications by eliminating detector baseline drift or cycling caused by pump hysteresis in discontinuous operating modes
