S 9425 and S 9430 Isocratic / Quaternary HPLC Pump

The Pumps S 9425 and S 9430 are available as Isocratic High - Pressure Pump and Quaternary Low - Pressure Gradient Pump.

The S 9425 and S 9430 pump is available with Micro, Analytical or Preparative pump head in Stainless Steel or PEEK.

The S 9425 Pump is delivered in a small housing.

The S 9430 Pump is delivered in a slightly larger housing (see technical specifications)

The size of the pump housing is adapted to the two different auto sampler (60 vials or 120 vials).

S 9432 Binary High - Pressure Gradient Pump

The S 9432 Binary - High Pressure Gradient Pump incorporates two pump systems with an optional Active High Pressure Mixer with adjustable chamber volume.

An optional integrated vacuum degasser removes dissolved gases in the eluents and prevents air bubbles in the system.

The system is available with Micro, Analytical or Preparative pump head in Stainless Steel or PEEK.

The S 9432 Binary - High Pressure Gradient Pump is delivered in a slightly larger housing than HPLC Pump S 9425 (see technical specifications).

The size of the pump housing is adapted to the two different auto sampler (60 vials or 120 vials).
