Year of introduction
Status available
Company Bio-Rad Laboratories
Categories Chromatography: LC/HPLC
The BioLogic DuoFlow chromatography systems offer flexibility with multiple system configurations, many optional upgrades, and a common control software that is intuitive and easy to follow.

Upgradable Systems Add Capability As Your Needs Change.
BioLogic DuoFlow modular components allow you to design your own biocompatible chromatography system to specifically meet both laboratory space and application requirements. As experimental requirements change, systems may be easily reconfigured and seamlessly upgraded with increased functionality such as higher flow rates, sophisticated detection capabilities, pH monitoring, trace comparison, and buffer blending.

BioLogic DuoFlow System Selection Guide
The F10 workstation includes an F10 pump for a flow rate of 10 ml/min at 3,500 psi. The F40 workstation includes an F40 pump for a flow rate of 40 ml/min at 1,000 psi. Flow rates for each pump can be doubled with the addition of the BioLogic Maximizer valve system.

BioLogic DuoFlow IQ/OQ
Bio-Rad offers qualification protocols and services for the BioLogic DuoFlow chromatography systems and their peripheral components, including the BioLogic Maximizer valve system for buffer blending, the BioLogic QuadTec UV/Vis detector, and the BioFrac fraction collector. Bio-Rad's IQ/OQ (installation qualification and operation qualification) protocols are designed to help custermers comply with US FDA regulatory requirements. Precedures are performed by factory trained and certified technicians using instruments and reagents traceable to NIST standards.

IQ service verifies that the BioLogic DuoFlow chromatography system is properly installed in your laboratory. OQ service tests the performance of the installed chromatography system and provides a record that confirms critical functions and safety features.

For more information on IQ/OQ for the BioLogic DuoFlow chromatography system, contact your local Bio-Rad sales representative.
