In the lab where I work, we usually use stir/heat plates along with magnetic stir bars to heat our compounds simultaneously. However, in terms of achieving a specific temperature range, the stir/heat plates are not ideally suited due to random fluctuations from being open to the air.

Therefore I want to use an oven to heat my solution to 125 degrees Celsius and also stir it at the same time.

The problem is I'm not sure how to to do this as stir/heat plate can not be in an oven and withstand the high temp. environment. I considered placing magnets on the perimeter of the reacting flask but realized the stir bar would eventually come to equilibrium.

Any ideas on how this can be done with general laboratory equipment?

Thanks in advance.

The standard way we do this in chemistry labs is to either use a heating mantle or setup an oil bath on a temperature-controlled stir/heat plate, then to place your reaction flask into that oil bath.
