Our powerful pump for preparative chromatography with a
- 100 ml pump head or
- 250 ml pump head or
- 500 ml pump head or
- 1000 ml pump head.
The Preparative Pump 1800 is a versatile HPLC pump with an interchangeable pump head available in different sizes and materials, including non-ferrous, biocompatible versions. This pump delivers constant flow rates for both analytical and preparative HPLC, including SMB purposes. Up to four pumps can be used to create a high pressure gradient system. This pump can also be used to form reliable and reproducible gradient profiles when equipped with the optional low pressure gradient valve module which is easily mounted in front of the pump head.
