Schambeck - Model Isocratic S 9425 and S 9430 -High Pressure HPLC-Pump
The Schambeck SFD GmbH Pump HPLC System is intended for the ambitious analyst. The system configu-ration is highly variable and several upgrade options make this system suitable for the whole range of analytical applications.
The HPLC Pump System is a very flexible and powerful HPLC solvent delivery system.
It´s modular setup makes the HPLC Pump System one of the most versatile pump systems on the market.
The Pumps S 9425 and S 9430 are available as Isocratic High - Pressure Pump and Quaternary Low - Pressure Gradient Pump (see flyer S 9425 and S 9430 Gradient Low - Pressure Pump). The S 9425 and S 9430 Isocratic High - Pressure Pump is available with Micro, Analytical or Preparative pump head in Stainless Steel or PEEK.
The S 9425 Isocratic High - Pressure Pump is delivered in a small housing. The S 9430 Isocratic High - Pressure Pump is delivered in a slightly larger housing (see technical specifications).
The size of the pump housing are adapted to the two different auto samplers (60 vials or 120 vials).
Stepper Motor
The S 9425 and S 9430 Isocratic High - Pressure Pump are driven by high - power stepper motors. The stepper motor has a much better resolution in the low - flow range than a conventional DC motor.
Lubrication
The S 9425 and S 9430 Isocratic High - Pressure Pump camshafts are constantly lubricated within a sealed chamber to guarantee long lifetime and low maintenance.
Dual-Piston Pump head
The S 9425 and S 9430 Isocratic High - Pressure 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 S 9425 and S 9430 Isocratic High - Pressure Pump heads incorporates an optional active piston back flushing system; this system is interchangeable with old Schambeck SFD GmbH pumps and does not require an additional Motor.
