Cool reactions from RDT's carousel
The Cooled Carousel Reaction Station range from UK-based Radleys Discovery Technologies (RDT) brings low cost parallel synthesis to applications that require sub-ambient temperatures as low as -70°C.

Fitting onto a standard IKA or carousel stirrer, it can simultaneously perform a choice of six or 12 cooled and stirred parallel solution phase or solid supported reagent based syntheses. Vigorous stirring and efficient mixing in each of the individual tubes or flasks (with working volumes from 10ml to 250ml) is provided by rare earth stirring bars. A central gas inlet and radial gas distribution system, combined with gas-tight PTFE caps, allow cooled reactions to be carried out under an inert atmosphere.
The carousel's robust HDPE 'cooling reservoir' is compatible with a wide range of manual freezing mixtures, including dry ice/acetone for efficient cooling from ambient down to -70°C.
The design of the cooling reservoir incorporates an insulated foam core, which maintains low temperatures for at least eight hours and protects the stirrer from freezing. It also reduces condensation and ice formation on outer surfaces.
A cover minimises the risk of 'solvent spitting' and spilling reactive reagents into the cooling mixture.
