LC-20AP
High flow rates (up to 150 mL/min) enable highly efficient, large-scale preparative fractionation.
Large-scale prep solvent delivery fully supports the preparative fractionation workflow including reinjection to assess purity.
Combine with an FCV-200AL low-pressure gradient unit to perform gradient analysis using up to four mobile phases.
