Cost effective personal synthesis stations for parallel solution phase chemistry and solid supported reagent based synthesis Innovative Stirring and Temperature Control - The patented Carousel provides heating, stirring and refluxing with inert gas control of twelve reaction tubes simultaneously. Efficient Refluxing - The integrated water cooled reflux head ensures even and extremely efficient refluxing, minimising solvent evaporation during synthesis for even the most volatile solvents such as ether. Cooling water is introduced through quick connect couplings with shut-off valve. Radial Gas Distribution/Inlet System - The radial gas distribution/inlet system is built into the centre of the reflux head to create an inert atmosphere for air sensitive/moisture sensitive chemistry. The single central inlet/outlet is designed for a tidy installation and easy purging.
