Mixing modules
Standard mixing and high sensitive mixing functions are included in the module. Each of mixing functions can be selected by connecting tubing for selecting flow line. Serial connection from flow line 1 to flow line 2 by an attaching tube enables to perform higher sensitive analysis.

Degasser modules

The Degasser removes gaseous components such as O,₂, N₂, and CO₂ from a solvent by passing the solvent through a special fluoropolymer membrane tube with the pressure outside the tube reduced. Because degassing by membrane separation is carried our under such mild conditions, the process has virtually no effect on the composition of the solvent.

Low pressure gradient unit
The Low pressure gradient unit is designed to be used with the model PU-2080 Intelligent HPLC pump. The PU-2080 Pump employs a slow suction, quick delivery method that provides extremely stable solvent delivery. The method's gentle suction action prevents cavitations in the pump head and is able to provide stable delivery of both volatile and viscose solvents.

Switching valves
The switching valves can be used to create for example a column switching unit.
Several units can be combined.
