S 1535 Preparative Pump
The S1535 pump is available in two flow rate models:
- 150 mL/min
- 250 mL/min
Two head material options:
- Stainless steel heads: Pressure range up to 400 bar
- PEEK heads: Pressure range up to 350 bar
The gradient mixer provides flexibility for gradient methods needing accurate and robust solvent mixing and The pump can be used for isocratic or gradient operation. It has an integrated display and keyboard and can also be used as a standalone instrument.
