Used Lab Equipment
We offer an assortment of refurbished and used Liquid Chromatography solutions ranging from HPLC, LC/MS to FPLC. Our systems can be customized to include almost any configuration of Autosamplers, Detectors and Pumps. Some of our leading manufacturers include Agilent, HP, Waters, GE, Amersham, Dionex and Shimazdzu. Our HPLC systems such as the Agilent 1100 and 1200 Series, Akta FPLCs, and the Waters Alliance & 600 series have the option of on site training, installation and extended warranties.
Hplc Quaternary Pump: 1-3 of 3
Agilent 1200 Series - G1311A HPLC Quaternary Pump
Cambridge ID #: 18525The G1311A is an optimized design ensuring virtually pulse-free and stable solvent flow with dual floating pistions. An inlet valve electronically activated and synchronized to piston stroke eliminates vapor formation with volatile solvents and is maintenance free. Instrument comes equipped with four solvent inlets with built-in gradient control.
Specifications:
- Configurable Flow Range: 0.001 – 10ml/min – in 0.001ml/min increments
- Flow Range: 0.2 – 10.0 ml/min
- Recommended pH Range: 1.0 – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel
- Gradient Formation: Low pressure quaternary mixing/gradient capability using proprietary high-speed proportioning valve. Delay volume 800-1100µl, depending on back pressure
