Carousel 12 Plus Reaction Station The patented Carousel 12 Plus Reaction Station simultaneously heats/cools, stirs and refluxes multiple samples under an inert atmosphere. An effective personal synthesis workstation for screening chemical reactions in parallel and solid supported reagent based synthesis. Heat, cool, stir and reflux multiple samples Accepts up to 12 glass tubes with a reaction volume from 1 ml to 20 ml Powerful, even stirring – fits on to a Carousel stirring hotplate Rapid heating to 220 ˚C and cooling to -78 ˚C Read more about the cooling options Quick to set-up and easy to use Easy viewing of tube contents during experiments Removable water-cooled reflux head An effective personal synthesis station Perform reactions under an inert atmosphere Fluoropolymer coating for chemical resistance and easy cleaning PTFE caps feature a ‘quick-thread’ for fast attachment to glass tubes Removable reflux head enables all reaction tubes to be to be removed simultaneously for transfer to a stand or for rapid post synthesis cooling ...when we talk about experiments for route scouting or optimisation, we refer to it as 'doing a carousel'. That is a reflection of how much it has positively changed our ways of working.Toxicological Testing Process Chemist, LundbeckRapid, efficient heating Locating onto the Carousel Stirring Hotplate, the Carousel 12 Plus will simultaneously heat up to 12 reactions from ambient to 180 ˚C (220 ˚C for short periods) with an accuracy of ±1 ˚C. The temperature can be controlled using the hotplate’s integral digital control or for greater accuracy, via an optional Pt1000 temperature sensor. The Pt1000 temperature sensor allows users to control by block or solution temperature. Either insert the temperature sensor into the aluminium base or through the Suba-Seal in the cap, directly into the reaction solution. Powerful, even stirring The Carousel’s patented design ensures powerful and equal stirring in all 12 reaction tubes. By positioning the tubes and magnetic stirrer bars equidistant from the stirring hotplate’s centrally located magnet, the Carousel ensures that all tubes are stirred at the same speed. This simple design coupled with high performance stirring bars provides powerful magnetic stirring from 100 to 1400 rpm. Efficient refluxing The Carousel’s integral water-cooled reflux/inerting head provides efficient cooling to all tubes; minimising solvent evaporation and loss. Water circulates inside the reflux head creating a cooling zone within the upper part of each tube, where vapours cool and condense back into the reaction. Quick-release water couplings with integral shut-off valves aid the connection of the water supply and minimise leaks.

The Carousel’s circular design allows easy rotation of the unit providing access to all tubes without having to lean into the fume hood. Removable reflux/inerting headAn innovative removable reflux/inerting head allows the removal of the head with the tubes in situ. This allows the reflux/inerting head to be easily transferred between the heated base, the stand or the cooling reservoir, providing the user with maximum flexibility. Chemical-resistant fluoropolymer coatingThe Carousel’s fluoropolymer coating offers heightened chemical resistance, minimises the effects of chemical attack and makes the surface easier to clean. Insulating plate improves heating and energy efficiencyThe 2-piece PTFE insulating plate sits over the Carousel’s heated base and acts as a barrier to heat loss for faster heating and energy savings of up to 36%. Carousel 12 Plus StandThe Carousel stand is designed to support the reflux/inerting head either with or without reaction tubes. The heavy duty metal stand is fluoropolymer coated for improved chemical resistance and ease of cleaning. The integral drip tray catches any dripping condensation from tubes and gives excellent stability. Use between reactions. Use when loading tubes. Use for reactions that require rapid air cooling. Operate under an inert atmosphereAn integral radial gas distribution system in the Carousel 12 Plus reflux/inerting head combines with individual gas-tight Easy-On PTFE caps, which screw directly onto each reaction tube, to distribute inert gas to all 12 tubes. To purge the tubes simply connect the central gas inlet via flexible tubing to a two-way stopcock then, by alternating between vacuum and inert gas, the tubes are quickly purged of unwanted air. This easy to use inerting feature is ideal for reactions requiring an air or moisture-free environment. Easy-On PTFE capsThe PTFE caps are an essential component of the Carousel 12 Plus system. Manufactured from a chemically-resistant PTFE the caps are attached to the reaction tube using a quick-thread and feature an Easy-On push connection to the radial gas system. The caps include an on/off valve for isolation and removal from the inert gas system. A replaceable silicone Suba-Seal septum allows the addition or removal of reagents or samples using a suitable syringe. Durable glass reaction tubesManufactured from high quality, heavy-walled borosilicate glass, the tubes are precision engineered to maximise heat transfer from the heated base and cooled reflux head. This ensures that all tubes are heated and cooled at the same rate. Standard tubes have a reaction volume of 5 to 20 ml. Reduced volume tubes have a reaction volume of 1 to 5 ml.

We will discuss a range of topics including how catalysis is cleaner and greener, solid supported catalysts, and working up multiple reactions with ease. Watch the webinar Webinar: Consistent Scaling UpScaling up chemical reactions can present a number of challenges with respect to efficient mixing, mass transfer, controlling exothermic reactions, heat transfer and reaction kinetics. In this webinar we discussed some simple guidelines which apply when scaling chemical reactions up or scaling down to predict or reproduce conditions observed in the larger scale manufacturing environment.
