Reactor-Ready and Lara vessels have a 15 mm bottom outlet valve (BOV) as standard. This is appropriate for the majority of customers.
However, if you would prefer a 25 mm BOV for your particular application (for example, because you are working with slurries), then we can manufacture custom Reactor-Ready or Lara vessels with 25 mm BOVs. (This option is not available for the smallest vessels.)
The vessels of our larger jacketed lab reactor, Reactor-Ready Pilot, have 25 mm BOVs as standard.
