Высокоэффективный жидкостный хроматограф Beckman System Gold

Product Description 10mm stainless steel 17ul capacity flow cell Programmable functions: wavelength range rise time auto zero etc. Wavelength range: 190 700 nm single channel programmable Wavelength accuracy: +/- 2 nm after calibration Beckman System Gold High Performance Liquid Chromatograph Overview 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&hellip,simply put you cant go wrong with GOLD!
