The CombiFlash Rf 200 system, 5-200 ml/min, 200 psi (with automatic injection valve). The Teledyne Isco CombiFlash Rf Flash Chromatography System brings you high-performance automation, programmable gradients, UV detection and peak separation, and automatic recognition of columns and collection tube racks. Its compact size makes it an excellent "personal system" and is well suited for operation in chemical fume hoods and other confined indoor spaces. For more advanced needs, the CombiFlash Rf is factory configured as a 5-200 ml/min (flow rate) 200 psi system that forms a binary gradient by automatically selecting two solvents from four inputs. This configuration features an automatic, self-cleaning injection valve for sample delivery and full-spectrum UV detection (200-360 nm) with secondary monitoring. An internal air pump is used for post-run column blowout, active solvent level detection, and full waste bottle detection. This Teledyne Isco 340CF Preparative Evaporative Light Scattering Detector (ELSD) is a modular component solution for the specific needs of preparative chromatography, allowing you to see compounds without chromophores with confidence. This detector offers advantages over other traditional ELSD systems:. Patented technology precisely controls temperature to optimize analyte detection (see Figure 1). The flexible signal filter option reduces baseline noise without affecting the resulting peaks. A straight drift tube and long-lasting laser ensure long-term reliability and require minimal maintenance. Low gas consumption — compatible with almost any gas supply (nitrogen recommended) Labprocure is responsible for this device.
