High and Low Pressure Gradient Mixers & Valves

Mixers - Valves

LG-2080-04 Proportioning Valve, 4-Solvent

Mixers - Valves

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.

MX-2080-32 High Pressure Dynamic Mixer

Mixers - Valves

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.
