The Agilent 1290 Infinity G4220A Binary Pump comprises two identical pumps integrated into one housing. Binary gradients are created by high-pressure mixing. A degassing unit is included for applications that require best flow stability, especially at low flow rates, for maximum detector sensitivity. The flow path of the pump has been optimized for minimal delay of gradients. Typical applications are high throughput methods with fast gradients on high resolution 2.1 mm columns. The pump is capable of delivering flow in the range of 0.05 -5 mL/min against up to 1200 bar. A solvent selection valve allows forming binary mixtures (isocratic or gradient) from one of two solvents per channel. Active seal wash is available for use with concentrated buffer solutions.

Quality
Our refurbished instruments are tested and repaired to meet factory specifications. We follow Installation Qualification, Operational Qualification, and Performance Qualification protocols (IQ, PQ and OQ).Expertise
Our team of skilled technicians are experts at fixing analytical instruments. We have been working with Agilent, Waters, Perkin Elmer, Sciex, Shimadzu, and Thermo instruments for many years. We are constantly updating our knowledge with the latest technology and information to enable us to deliver the best support in the industry. We provide value added support and qualification/validation with all our instruments. We endeavor to develop strategic partnerships with our clients so that they consider our team as an extension of their employees. We are an affordable alternative to many normally expensive business projects.Warranty and Support
We offer warranty on all refurbished instruments. Warranty starts at 3 months, with the option to extend the period. While your instrument is on warranty, we will provide Email (support@spectralabsci.com) and phone support and troubleshooting if you require assistance. If there is ever anything wrong with the equipment, we will replace it. Warranty begins from the date your equipment is successfully delivered. Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty.We will match our warranty duration with our competitors.
