BioFrac Fraction Collector
BioFrac Fraction Collector

The BioFrac fraction collector can be used for basic or complex fraction collection schemes at flow rates <100 mL/min. Available stand-alone or with the BioLogic DuoFlow and LP systems, this fraction collector offers flexibility with numerous collection rack options ranging from an icebath/microplate rack to a prep-20 preparative scale rack for large volume collection. Collection in time, drop, or volume mode with peak detection, time windows, or a combination of both.

BioLogic Maximizer
BioLogic Maximizer

The BioLogic Maximizer expands the capabilities of the BioLogic DuoFlow systems. It enables buffer blending, doubled flow rates, and twice the valve capacity of the standard BioLogic DuoFlow system.

BioLogic DuoFlow UV Detector

This high-resolution portable UV detector and conductivity monitor can be moved easily to the column outlet. The conductivity monitor sits in a holder at one end of the detector.

BioLogic DuoFlow pH Monitor
BioLogic DuoFlow pH Monitor

This pH monitor enables real-time monitoring of pH conditions (pH 1–14) during a sample run. It consists of high-precision calomel electrodes which are compatible with buffers such as Tris that are incompatible with Ag/AgCl electrodes. It is a biocompatible PEEK flow cell with a swept volume of approx 80 µL that is capable of withstanding flow rates to 80 mL/min. The monitor is included with all BioLogic Maximizer™ and Pathfinder® systems and is available as an option on the BioLogic DuoFlow™ and BioLogic DuoFlow QuadTec™ systems, where it connects via the Signal Import Module (SIM).

BioLogic Signal Import Module (SIM)
BioLogic Signal Import Module (SIM)

This optional module allows import of an analog signal (up to 2.5V) from a pH electrode or other external detector (such as a UV, refractive index, or fluorescence monitor). The BioLogic DuoFlow software accommodates two SIMs and can display four data signals simultaneously.

BioLogic DuoFlow Valves
BioLogic DuoFlow Valves

High- and low-pressure valves are available. High-pressure sample injection (AVR7-3) and stream select (AVR9-8) valves use the patented MBB (make-before-break) design that prevents pressure spikes when the valve rotates from one port to another, eliminating baseline interference. The feature is beneficial when using fragile low-pressure columns or flow-sensitive detectors and prevents pump shutdown due to transient pressure conditions.

EZLogic Integration Software
EZ Logic Integration Software

EZLogic integration software adds quantitative functions to basic BioLogic DuoFlow software with the same easy-to-use graphical interface. The software provides tools necessary to quantitate samples, integrate and overlay chromatograms, determine retention times, view results, and generate customized reports. Graphical capabilities include split-screen chromatogram views, zooming, multiple parameter annotation, and color selection.

• Included as standard. º Option or upgrade.  

The BioLogic DuoFlow 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. These systems can be used on the laboratory bench or in a coldroom.

The BioLogic DuoFlow Pathfinder 80 system includes:

  • F40 workstation
  • BioLogic Maximizer valve system for flow rates of up to 80 ml/min
  • BioLogic QuadTec UV/Vis detector for simultaneous monitoring of four wavelengths ranging from 190–740 nm (with deuterium lamp at 190–370 nm and optional halogen lamp at 370–740 nm)
  • BioLogic DuoFlow pH monitor for real-time monitoring of pH conditions during a run
  • BioFrac fraction collector for the widest range of collection capabilities

A BioLogic Maximizer mixer, MX-1 mixer, 3-tray rack, AVR7-3 sample inject valve, fittings kit, system cable 25, conductivity monitor, starter kit, UNO Q1 column, diverter valve, two F1 racks, and instructions are also included.

The Dell PC controller enables easy communication with the workstation and peripheral devices via an external USB Bitbus communicator. The controller includes the Windows XP operating system, application software, keyboard, mouse, and high-resolution flat-panel monitor.

BioLogic DuoFlow modular components allow the system to meet both laboratory space and application requirements; as requirements change, systems may be easily reconfigured and seamlessly upgraded with increased functionality, such as higher flow rates, sophisticated detection capabilities, pH monitoring, column scouting, and buffer blending.
