Pure C-810 / C-815 Flash are advanced, powerful flash systems which allow more purification in less space thanks to their compact design. They ensure safety on the highest level and can be operated outside of a fume hood, as they are equipped with a closed fraction collector bay. Also, they are furnished with leak and pressure sensors as well as with a remote control to reduce exposure to the lab environment. Pure C-815 is additionally equipped with integrated ELSD that is dedicated to flash chromatography and exhibits the lowest sample loss in the market. The Pure Chromatography Line by Buchi Labortechnik AG embodies flash and prep HPLC instruments in one system, easy to use for any flash or prep HPLC application. Typical Applications: Purification after synthesis, preparative isolation of a compound from a formulation, purification of APIs after organic synthesis, screening o ...
