The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Bio-Rad - Model: BioLogic BioFrac - Condition: Used and in Excellent Condition - Price: Quote only - Availability: Not in Stock - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 23.3 lb, estimated - Shipping dimensions: 24X20X12 in, estimated ## Categories - Lab & Analytical > Chromatography (primary) - Lab & Analytical > Autosamplers ## Details ### Includes - Diverter Valve; Part Number: 741-0008 - Rack Positioning Tray Input Voltage: 100-240 VAC ## Overview Automated laboratory instrument for collecting fractionated components separated through liquid chromatography. Interfaces with chromatography systems via analog signals or digital connections. Compatible with various column configurations and Bio-Rad's BioLogic chromatography platforms. Features programmable collection parameters including time, volume, and peak detection modes. Accommodates multiple rack formats for test tubes, microplates, and collection vessels. Supports drop counting or volumetric collection methods. Enables fraction collection based on UV absorbance, conductivity, or pH signal thresholds. Used in protein purification, antibody isolation, enzyme separation, and biomolecule fractionation workflows. ## Function Automates fraction collection based on time, drop count, or tube number, compatible with various chromatography systems. Hardware includes a fraction collector unit with a moving rack, collection tubes, and a control system for managing collection parameters and interfacing with detectors and pumps, connected via serial or Ethernet. Common applications are protein purification and chromatography. ## Platform The fraction collector automates the collection of liquid chromatography eluent. It interfaces with chromatography systems via analog signals for fraction triggering based on time, volume, or peak detection, and digital signals for control. The system is controlled via a built-in keypad and display or external software via serial communication, operating within a laboratory environment on a benchtop. ## Application Automates the collection of chromatographic fractions during protein purification and biomolecule separation processes. Compatible with FPLC, HPLC and low-pressure chromatography systems, collecting samples based on time, volume, or peak detection parameters. Features programmable collection patterns, adjustable rack configurations, and drop detection capabilities for precise fraction isolation. Commonly used in research laboratories for protein purification, enzyme isolation, antibody fractionation, peptide separation, and biomolecule characterization in pharmaceutical development, academic research, and biotechnology applications. ## Accessories BioLogic LP/DuoFlow system integration.
