Bio-Rad Econo Gradient Pump

The Bio-Rad Econo Gradient Pump is a used dual piston liquid chromatography pump built to deliver precise solvent gradients for column based protein purification. It is commonly used as the fluid delivery core of a low pressure chromatography setup, providing steady, programmable flow for applications such as ion exchange, gel filtration, and affinity purification. Its design emphasizes reliable, drift free gradient formation over long purification runs. Lab technicians value this pump for its straightforward operation and compatibility with a range of Bio-Rad chromatography accessories, including UV detectors and fraction collectors, making it easy to build a complete purification train around it. The dual piston mechanism supports both isocratic and gradient elution modes, giving researchers flexibility to match pump behavior to the separation chemistry at hand. Its rugged construction reflects its original purpose as a dependable workhorse component in biology and biochemistry labs running frequent purification cycles. This Econo Gradient Pump is offered used, pulled from a working laboratory chromatography setup, and sold in functional condition. It is a good option for labs looking to repair, replace, or add capacity to an existing Bio-Rad chromatography line without paying for a brand new pump module. Buyers building a custom purification system from individual components will find this pump a solid and economical fluid delivery choice.
