S 170 EXPERTPUMp System S 1125 HPLC HPLC SYSTEM The Sykam S 1125 HPLC Pump System is a very flexible and powerful HPLC solvent delivery system. The system is available as Isocratic HPLC pump and Quaternary Gradient Pump with optional integrated online vacuum degasser. Quaternary Gradient Pump The S 1125G Quaternary Gradient Pump incorporates an active low pressure mixer with adjustable mixing volume. The mixing chamber volume can be freely adjusted. An optional integrated vacuum degasser removes dissolved gases in the eluents and prevents air bubbles in the system. Pump Mechanic Lubrication Stepper Motor The S 1125 camshaft is constantly lubricated within a sealed chamber to guarantee long lifetime and low maintenance. The S 1125 is driven by a highpower stepper motor. The stepper motor has a much better resolution in the low-flow range than a conventional DC motor. Optional: Active Piston Backflushing The S 1125’s pump head incorporates an automatic piston backflushing system; this system is interchangeable with old Sykam pumps and does not require an additional motor. Dual-Piston Pumphead The S 1125 pumps use a dual-piston pumphead for low pulsation. Together with electronic pressure compensation the S 1125 pumps are suitable for all analytical tasks in HPLC and GPC.

The system is available with Micro or Analytical pumphead in Stainless Steel or PEEK.
