About This Product
Unlike a closed batch, this reactor has a single input stream: a measured amount of one reactant is charged first and the other is added from the feed tank during the run. Holding the bath constant keeps the reaction mass isothermal and the stirrer keeps it perfectly mixed, while samples taken by pipette after fixed intervals track progress.
Frequently Asked Questions
How does a semi-batch run differ from a batch run?
The reactor is charged with a measured quantity of one reactant before the start, and the second reactant is then fed in from the feed tank, so the system is semi-closed with one input stream.
What compressed air supply is needed?
Compressed air at 2 bar and 0.25 CFM moves the feed. The air line carries a pressure regulator, Bourdon gauge and safety valve.
