Abstract
The apparatus acts like a centrifuge spreads the sample in the form of a film over a plate. A unit is provided to take the excess liquid thrown off the plate during rotation. A drive mechanism rotates a sample holder at roughly the same speed as the plate. Pref. the excess liquid unit comprises porous material in a housing. Pref. the plate and the excess liquid unit are supported by separate mechanisms which can be raised and lowered independently of each other to facilitate handling of the sample plate. The process is known in the laboratory as the production of a film or a film-like coating.
