A clear idea
You have a clear idea of what a magnetic stirrer head has to do for you. It must be easy to mount on your autoclave lid, should withstand high pressures and temperatures and at the same time offer a high degree of safety. Of course, in addition to the choice of torque, you also expect speed measurement directly on the output shaft, a gas supply and high flexibility when replacing the stirring elements. All this is no problem for the macfix, it combines all properties.
