Heat flow can be equilibrated quickly bystirring vigorously. Big hunks of metal are not needed.
vigorous stirring of fluid, (which can be air), around your test vials is just as good
as fancy machined metal for transferring heat. Controlling heat is easy for microcontrollers,
just throwing switches, (and needing only cascades of heavier and heavier switches to get up
to high powers of some heaters).
