What is the height of Reactor-Ready and Reactor-Ready Duo? Current/existing Reactor-Ready and Reactor-Ready Duo, with Radleys RS overhead stirrers (or Heidolph RZR stirrers) The framework is 1080 mm high, so if you position the overhead stirrer on the frame so that its top is level with the top of the support rods or lower, this will be the system height. NB. If you have a particularly long vessel, and/or particularly tall glassware lid accessories, your total system height will be taller than this. UPDATE: longer support rods for use with new Hei-TORQUE stirrer motors Following the discontinuation of Heidolph RZR and Radleys RS overhead stirrers and the introduction of the Heidolph Hei-TORQUE range, we have designed longer support rods (poles) for Reactor-Ready and Reactor-Ready Duo. This is to enable use of the larger Hei-TORQUE stirrer motors with our longest vessel (5 L standard shape), whilst having space under the vessel to remove the piston. Reactor-Ready and Reactor-Ready Duo systems will start being supplied with these longer rods later in the year. With the longer support rods the framework increases to 1103 mm tall, and with Hei-TORQUE Ultimate (Hei-TORQUE Precision) (the largest stirrer motor), the total system height is 1195 mm (excluding any tall glassware). This gives a 115 mm clearance below the piston of the RR135000 5 L standard shape vessel.
