High and Low Pressure Gradient Mixers & Valves

LG-2080-04 Proportioning Valve, 4-Solvent The model LG-2080-04 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-2080-04 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 SUS, fluoropolymer and PEEK only, permitting a wide range of solvents to be used. Specifications Number of solvents: 4 Precision of solvent composition: +/-0.2% (in the composition range of 10 to 90%) Precision of linear gradient: +/-1% (in the composition range of 10 to 90%) Flowrate range: 0.3 ml/min to 3 ml/min Power requirements: AC100 to 240V +/-10%, 50/60 Hz, approx. 20VA Dimensions: 150mm (W) x 72mm (H) x 470mm (D) Weight: Approx. 5kg MX-2080-31 Static High Pressure Mixing Module The MX-2080-31 Mixing module is designed to perform high-pressure gradient mixing. Both standard mixing and high sensitivity mixing functions are included in the module. Each mixing function can be selected by connecting tubing to selecting flow lines. Specifications 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 - 20ml/min Internal volume flow line1 : 1.25ml   flow line 2 : Approx. 3ml Dimensions 150(W) x 72(H) x 470(D) mm Weight Approx. 3kg

LG-2080-02 Proportioning valve, 3-solvent The model LG-2080-03 Low pressure gradient unit is designed to be used with the model PU-2080 Intelligent HPLC pump. This unit is identical to the LG-2080-04 and can be configured for gradients up to 3 solvents.. Specifications Number of solvents: 3 Precision of solvent composition: +/-0.2% (in the composition range of 10 to 90%) Precision of linear gradient: +/-1% (in the composition range of 10 to 90%) Flow rate range: 0.3 ml/min to 3 ml/min Power requirements: AC100 to 240V +/-10%, 50/60 Hz, approx. 20VA Dimensions: 150mm (W) x 72mm (H) x 470mm (D) Weight: Approx. 5kg   MX-2080-32 High Pressure Dynamic Mixer The MX-2080-32 is a high pressure dynamic mixer, capable of mixing up to 3 solvents under high pressure. By changing the chamber  capacity, the instrument can be used in various applications from semi-micro HPLC with a volume down to 20uL to semi-preparative HPLC. For analytical flow rates the standard chamber capacity is 1.5ml. Chambers for semi-micro HPLC and semi- preparative HPLC are available as options. Specifications Solvent mixing method Mixing by rotation of stirrer bar Number of piping inlets 3 (Max.) Rotation speed setting FAST : Approx. 2000rpm   MID : Approx. 1500rpm   SLOW : Approx. 1000rpm Chamber capacity 1.5ml (Standard)250µl, 400µl, 5ml, 3ml (Option) Rated power AC100 to 240V +/-10%, 50/60Hz, 36VA Dimensions 150(W) x 72(H) x 470(D) mm Weight Approx. 4kg
