The Carousel 6 workstation facilitates both small and large scale syntheses, operates at elevated or sub-ambient temperatures, and copes with almost any reaction medium effectively. It uses very little fume cupboard space, is easy to set-up, and requires minimal training time. The unit allows each flask to be clearly visible and easily accessible for addition of reagents and solvents. Drop-in aluminium inserts enable reaction flasks to be quickly inserted or removed. The workstation has no electrical or moving parts.
