AZURA 2.1L Preparative HPLC Pump
The AZURA range of preparative HPLC pumps have
been developed by Knauer to replace the highly
successful 1800 HPLC Pump. The standard pump is
supplied with the pumphead of your choice.
Four interchangeable pump heads are available
offering maximum flowrates between 100 and 1000
ml/min. Built-in back-flushing capability gives
greatly improved reliability for unattended
Designed for Reliability
The AZURA P 2.1L preparative HPLC Pump design
ensures minimum downtime and constant precise
flow rates for practically any preparative HPLC
The standard AZURA 2.L pump is designed for operation using software control via a PC, addition of the optional
touch-screen control module offers the control needed for reliable and reproducible gradient operation without the
need for an external PC. Multiple pumps can be used to form a high pressure gradient system, low pressure gradient
system options are also available for either binary or ternary gradients.
Easily Integrated into Systems
The AZURA 2.L HPLC Pump is of modular design, easy-to-use and easy-to-maintain, which allows it to be integrated
easily into existing systems as a module. Built-in leakage detection monitors the system for any signs of eluent
leakage thus offering additional safety in unattended operation.
Both cooling and heating options for pump heads and the necessary thermostat connections are available upon
