What are the minimum/maximum working volumes of each Reactor-Ready, Reactor-Ready Pilot or Lara vessel? Our general guidelines are that: The maximum working volume is about 10% higher than the nominal volume (the one stated in the vessel description) The minimum working volume is around 20% of the maximum volume Please note, if you want to work at a range of volumes, we would advise that you purchase a range of vessel kits as appropriate for those volumes. Each vessel kit contains a Pt100 temperature probe and stirrer shaft/rotor of a suitable size for that vessel. It’s quick and easy to swap vessels in Reactor-Ready, Reactor-Ready Duo, Reactor-Ready Pilot and Lara, unlike traditional jacketed lab reactors – so you do not need to stick with one vessel per reaction system.
