The effects of heat and air are determined by physical tests measured before and after the rotation treatment.

Therefore a moving thin film of a sample is heated in an rotating flask of a rotary evaporator. The rotation shall prevent a surface hardening.

EN 12 607-3:
The samples are cooled down in a desiccator.

The change in sample mass (by analytical balance) and the changed properties of binders (by Penetration, Softening-Point, Viscosity).
