Dionex BioLC GS50 Microprocessor-Controlled Gradient Pump for HPLC Applications

The Dionex BioLC GS50 Gradient Pump is a microprocessor-based, serial-piston gradient pump designed for high-pressure liquid chromatography (HPLC) and advanced biotechnology applications, including molecular diagnostics and bioprocessing workflows. This pump offers pulse-free eluent delivery with precise flow control and compositional accuracy essential for sensitive analytical procedures.

Key technical features include:

• Flow accuracy of <1% of set value or ±2 µL/min
• Flow precision better than 0.2%
• Compositional accuracy within ±1%, enabling reliable mobile phase gradients
• Maximum operating pressure of 35 MPa (5000 psi) to support high-throughput and high-resolution chromatographic separations
• Ability to mix up to four mobile phase components in variable modes: isocratic, isocratic proportioned, linear ramp, step, curved gradients, or combinations thereof
• Low delay volumes (<400 μL for low delay, <800 μL standard), critical for fast gradient response in biopharmaceutical and synthetic biology research
• Incorporates a Digital Signal Processor (DSP) to deliver high-speed, accurate flow control, making it ideal for live-cell imaging sample preparations, fluorescence analysis, and other biotechnology-driven analytical requirements

Note: The unit is sold without pump heads, as removed from a working BioLC system, offered at a reduced price. Compatible with the Dionex BioLC system components (available separately), this pump is widely used in synthetic biology and molecular cloning workflows, playing a crucial role in biomanufacturing quality control and molecular separation processes.

This pump is an essential instrument for laboratories performing molecular diagnostics, biomedical engineering, and cell imaging that require reproducible and highly controlled mobile phase delivery in liquid chromatography.
