Supports a Range of Applications
from High-Precision Analytical to Semi-Preparative
LC-40D • This solvent delivery unit can handle flow rates ranging from those used in analytical
scale to those used in semi-preparative (up to 10 mL/min).
• High-precision analysis is possible even in the semi-micro flow-rate range.
Supports Semi-Preparative and Recycle Preparative
LC-20AR • This solvent delivery unit can handle flow rates used in semi-preparative scale (up to 20
mL/min).
• Using a recycle kit enables semi-preparative recycling.
Supports Large-Scale Preparative Fractionation
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.
