Abstract
The invention relates to a method of treating at least one polymer item comprising treating said at least one item by liquid CO2 in a vessel comprising a rotary basket. The method comprises - providing at least one polymer item, - applying the item(s) in a container, - fixing the container non-concentrically in the rotary basket, - closing the vessel and treating the polymer item(s) with liquid CO2 under at least partial rotation of the basket with a rotation axis which is substantially horizontal or up to about 45 degree from a horizontal plane for a predetermined time. By the method a very homogenous extraction of residuals can be obtained.
