LG-2080-04/02
Low pressure gradient units
Proportioning valves controlled by the PU-2080

The Model LG-2080-02 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. The LG-2080-02 exploits the slow suction action of the PU-2080 pump to allow highly precise solvent mixtures to be easily produced. The delivery unit is fabricated from fluoropolymer and PEEK only, permitting a wide range of solvents to be used.

• Up to 4 solvents (LG-2080-04)
• Up to 3 solvents (LG-2080-02)
• Precision of solvent composition: ± 0.2%
• Precision of linear gradient: ± 1%
• Flowrate range: 0.3 mL/min to 3 mL/min
• Solvent-wetted materials: PTFE and PEEK

MX-2080-31  
3-solvent high pressure mixer
Static mixing

The Model MX-2080-31 Mixing module, which is designed to perform high-pressure mixing gradient system. Both standard mixing and high sensitive mixing functions are included in the module. Each of the 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.

• Solvent mixing method: Static type
• Flow lines for mixing: Flow line 1, flow line 2, flow line 1 plus flow line 2
• Flow rate: 0.5 - 20 mL/min
• Internal volume:
• flow line 1: 1.25 mL
• flow line 2: Approx. 3mL
• Dimensions: 150(W) x 72(H) x 470(D) mm
• Weight: Approx. 3kg

MX-2080-32   
3-solvent high pressure mixer
Dynamic mixing

The MX-2080-32 is a high pressure mixer, capable of mixing up to 3 solvents under high pressure, for HPLC. Since mixing is done forcefully by a stirrer, the instrument is capable of mixing solvents that could not be sufficiently mixed by conventional static mixers. By changing the chamber (mixing section) capacity, the instrument can be used in various applications from semi-micro HPLC to semi-preparative HPLC. The standard chamber capacity is 1.5 mL. Chambers for semi-micro HPLC and semi-preparative HPLC are available as options.

• Solvent mixing method: Mixing by rotation of stirrer bar
• Number of piping inlets: 3 (Max.)
• Rotation speed setting:
  - FAST: Approx. 2000 rpm
  - MID: Approx. 1500 rpm
  - SLOW: Approx. 1000 rpm
• Chamber capacity:
  - 1.5 mL (Standard)
  - 250 µL, 400 µL, 5 mL, 3 mL (Option)
• Rated power: AC100 to 240V +/-10%, 50/60 Hz, 36 VA

DG-2080-53/54 In-line Degasser
Vacuum degassing by membrane separation

The DG-2080-53 Degasser removes gaseous components such as O2, 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 out under such mild conditions, the process has virtually no effect on the composition of the solvent. In addition, this method is highly efficient, yielding results similar to that of degassing by the helium sparging method.

The DG-2080-54 Degasser removes gaseous components such as O2, 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. In addition, this method is highly efficient, yielding results similar to that of degassing by the helium sparging method.
