Overview
The SepaBean™ machine 2 is an advanced medium-pressure chromatography model with a higher flow rate of 300 mL/min and up to 500 psi (34.5 bar) backpressure tolerance. The system features a four-line binary gradient accommodating any two-solvent combination, with an option to add a third solvent as a modifier up to 15 %.-
Higher Flow Rate and Backpressure
Achieves 300 mL/min flow rate and 500 psi
(34.5 bar) for faster and tougher separations. -
Wireless Control and Operation
Allows remote control via mobile devices, ideal for light-sensitive or isolated experiments.
-
Easy Flash Method Development
Optimises and transfers separation conditions from HPLC and TLC for efficient, scalable purification.
-
Optional ELSD Detector
Optional ELSD expands detection capabilities to cover a wider range of sample types, including non-UV-active compounds.
