Carousel 12 Plus Reaction Station


Carousel 12 Plus Reaction Station

The patented Carousel 12 Plus simultaneously heats/cools, stirs and refluxes multiple samples under an inert atmosphere.
An effective personal synthesis station for parallel solution phase chemistry and solid supported reagent based synthesis.


  • 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.
  • Quick to set-up and easy to use.
  • Easy viewing of tube contents during experiments.
  • Removable water-cooled reflux head.
  • 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 allows reaction tubes to be transferred between heated base, cooled base or stand.

Rapid, efficient heating
Locating onto the Carousel Stirring Hotplate, the Carousel 12 will simultaneously heat up to 12 reactions from ambient to 180 ˚C (220 °C for shorter 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 Pt 1000 temperature sensor. Choice of three hotplates.

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 equi-distant from the stirring hotplate's centrally located magnet, the Carousel ensures that all tubes are stirred at the same speed.

Efficient refluxing
An 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 to the reaction tube.

Operate under an inert atmosphere
An integral radial gas distribution system in the reflux/inerting head combines with individual gas-tight Easy-On PTFE caps to distribute inert gas to all 12 tubes. This easy to use inerting feature is ideal for reactions requiring an air or moisture-free environment.

Easy viewing of tube contents
The Carousel 12 Plus features viewing slots in the heated base that allow an excellent view of tube contents during synthesis. The vertical slots allow natural light into your reaction so you can see any changes of state and be certain your stirring is adequate. The Carousel's circular design allows easy rotation of the unit providing access to all the tubes without having to lean into the fume hood.

Easy-On PTFE caps
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 samples or reagents from the tube.

Durable glass reaction tubes
Heavy-walled borosilicate glass reaction tubes are precision engineered to maximise the effectiveness of the temperature transfer from the heated base and cooled reflux head. The standard tubes have a reaction volume of 5 to 20 ml (reduced volume tubes 1 to 5 ml).

Chemical resistant fluoropolymer coating
The Carousel’s fluoropolymer coating offers heightened chemical resistance, minimises the effects of chemical attack and makes the surface easier to clean and keep free from contamination.

Removable reflux/inerting head
An 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.

Carousel 12 Plus Stand
The 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.
