SRI - Model S 9425/S 9430/S 9432 -HPLC Pump System
The S 9425/S 9430/S 9432 HPLC Pump System is a highly adaptable and potent HPLC solvent delivery system. It is one of the most adaptable pump systems on the market thanks to its modular design. Isocratic or Quaternary Gradient Pump for S 9425/S 9430 and a Binary High-Pressure Gradient Pump S 9432 are the conceivable setups.
Stepper Motor
The HPLC pump system is driven by a high-power stepper motor. The stepper motor has a much better resolution in the low-flow range than a conventional DC motor.
Active Mixer
The low-pressure and high-pressure gradient module has an active mixer to achieve highly precise and accurate gradient results.
Lubrication
The HPLC pump’s camshaft is constantly lubricated within a sealed chamber to guarantee long lifetime and low maintenance.
Dual-Piston Pumphead
The HPLC pumps use a dual-piston pump head for low pulsation. Together with electronic pressure compensation the pumps are suitable for all analytical tasks in HPLC and GPC.
Optional: Piston Back-flushing
The HPLC pump’s head incorporates an optional active piston back-flushing system; this system is interchangeable with old Sykam pumps and does not require an additional motor.
