Low-Pressure Liquid Chromatography Systems

 

BioLogic LP system

The BioLogic LP low-pressure chromatography system is used for biomolecule purification. Its compact design minimizes the workspace required in the coldroom or on the laboratory bench. The system includes both 254 and 280 nm filters for nucleic acid and protein detection, and a conductivity cell to monitor gradient progress.

Key Feautures
The system houses a peristaltic pump with a flow rate range of 0.05–40 ml/min (20 ml/min per channel; dual-channel peristaltic pump) and maximum backpressure of 30 psi (0.2 MPa); the system is compatible with Econo-Column low-pressure chromatography columns, UNOsphere, Bio-Gel P, and Macro-Prep chromatography media, Bio-Scale Mini and Econo-Pac cartridges, Amersham HiTrap cartridges, SOURCE media, and all other low-pressure chromatography media. Addition of an SV-5 buffer select valve allows selection of up to 5 buffers and automated sample separation and loading of large sample volumes.
The system can collect into eighty 13 x 100 mm tubes or microtubes using the Model 2110 fraction collector, or collect into virtually any size container, from microplates to carboys, using the BioFrac fraction collector. In addition, the BioLogic LP system supports the use of many collectors from other manufacturers.
The BioLogic LP system has IEC 61010 safety certification.
LP Data View software captures data, multitasks, and prints data from any computer that runs on Windows 95, 98, Me, NT version 4.0, 2000, or XP operating systems. The system stores up to 50 methods; each method can include up to 50 pump steps and 50 fraction collection steps.

Econo Gradient Pump

The unique Econo™ gradient pump is suited for any low-pressure protein purification system. It is the only stand-alone peristaltic pump capable of isocratic and gradient elution applications.
The Econo gradient pump is a two-channel bidirectional pump that is ideal for preparative applications and for scaling up the purification of recombinant proteins. It works seamlessly with other peripherals, such as chart recorders, the Model 2110 and BioFrac™ fraction collectors, the Model EM-1 Econo UV monitor, and the Model EG-1 Econo gradient monitor. Configure the system according to your needs and budget using the Econo gradient pump combinations as a starting point.

• Simple setup and programming, including gradient programming in either time or volume mode
• Control of an optional diverter valve for waste or fraction collection (especially useful with size exclusion runs that have particularly large void volumes)
• Stop/start control of fraction collectors; Hold and Pause available with certain collector types
• Stop/start, pen up/down control of chart recorders
• Control of an optional splitter valve by percent-split increments
• Automated calibration procedures for a variety of tubing sizes
• Luer-Lok fittings for inexpensive, simple, and fast tubing connections
• User-adjustable LCD screen contrast, revolution counter to determine tubing wear, and keypress confirmation beep
