Bio-Rad Bio-Logic Duo-Flow Chromatography System ***This instrument was tested to specifications. Unit has some wear and rust buildup from normal use. Everything pictured included. (Does NOT include USB Bit Bus communicator or software). See photos for details. Includes: Bio-Logic Duo-Flow Auto Injection Valve AVR7-3 Auto Select Valve AVR9-8 (Qty:2) Select Valve SV5-4 (Qty:2) Optics Module II OM-11 The Bio-Logic Duo-Flow chromatography system is specifically designed for the high-resolution purification of proteins, peptides, and other biomolecules where recovery of biological activity is of primary concern. The flexible control architecture allows the seamless integration of a wide variety of configurations with other Bio-Rad and non-Bio-Rad components to meet your purification requirements. The Bio-Logic Duo-Flow family of chromatography systems offers flexibility with multiple system configurations, many optional upgrades, and a common software platform that is intuitive and easy to follow. Suitable for analytical and preparative chromatography. Bio-Logic Duo-Flow Systems. These are medium pressure laboratory scale chromatography systems for protein purification. These systems are modular, capable of running at high flow rates (0.0580 ml/min) with back pressures up to 3,500 psi, with pH monitoring, buffer blending, and column scouting capabilities. It can be used in conjunction with a fraction collector for unattended operation. Features: Flexibility of setup. A space saving modular design that is stackable enables configuring the system to meet your exact needs and fit into your desired bench space. Trays and vertical bars are. moveable and removable. Horizontal bars can be placed in the optimal position for valves, columns, detectors, etc. The system fits easily into a cold box. Modular components provide an easy upgrade path to fit all applications and financial requirements. For example, the Duo-Flow Basic system may be purchased and upgraded to a Pathfinder system as needed. Intuitive, user-friendly software programming. Users become experts in only a few runs. Easy to set up new devices/instruments, On screen Help. Easily accessed extensive, detailed explanations and troubleshooting guide. USB Bit bus Communicator. (Not included) Bit bus communication allows users to connect their own USB compatible PC computer running Windows 2000 and the Duo-Flow version 4.0 or higher software. Buffer Blending for pH methods development applications. The Maximizer add-on component provides this additional capability to the Duo-Flow system. pH Monitor. The optional in-line Bio-Logic pH monitor allows direct monitoring of pH conditions during a run and comes with the Maximizer. It has a Calomel sealed electrode with both pH and reference electrodes in a single body. The sealed reference design eliminates the need to add electrolyte solutions and minimizes reference dry out. The electrode is fully compatible with buffers, like Tris, that may not be compatible with Ag/AgCl (silver/silver chloride) containing electrodes. It has a PEEK biocompatible flow cell. Flow Rate Flexibility. The Workstation has pump heads that permit higher or lower flow rates. The Duo-Flow system may be equipped with F10 pump heads for slower flow rates from 0.01 ml/min, or F40 pump heads for higher flow rates to 80 ml/min, when used with the Maximizer. Detection Flexibility UV detector with fixed 254 nm and 280 nm filters, long life mercury lamp, and additional drop-in expansion filters available. UV detector can be expanded to 214 nm filter with zinc lamp. Quad Tec UV/Vis detector analyzes samples simultaneously at 4 different wavelengths from 190-370 nm with a deuterium lamp or 370-790 with a halogen lamp. Third party detectors, such as refractive index or fluorescent, may be utilized with our Duo-Flow systems via a SIM or Maximizer. Conductivity Monitor monitors salt concentration to assure reliable gradient formation and pump functions. Multiple Valve Capabilities Workstation provides connection for 3 low pressure and 3 high pressure valves. Workstation with the addition of the Maximizer doubles the capacity to 6 low pressure and 6 high pressure valves.
