The following illustrations and descriptions refer to the instrument model and are drawn from brochures. They do not represent the scope of delivery. Please refer to the text of the offer for the exact scope of delivery.

Beckman System Gold(R) HPLC systems incorporate the latest technological advances in hardware design. The solvent delivery modules are built with the digitally controlled rapid refill pump design with automatic compressibility compensation that has received multiple patents. These features produce smooth flow from microbore to semi-preparative flow rates and the high-pressure mixing design eliminates the need for constant helium sparging or degassing. The pumps are combined with high-sensitivity UV/VIS and diode array detectors and autosamplers with automation capability to build HPLC systems that have a reputation for the best performance ease of use and troubleshooting and longevity due to a solid and reliable design
