摘要
A method for removing a filter unit (9) from a laboratory extraction hood (1) in safety conditions for an operator and for the surrounding environment comprises the steps of: a) sprinkling the filter unit (9) with a solidifiable encapsulating solution (15); b) waiting for a solidification period so that the solution (15), solidifying, prevents the filter unit (9) from releasing into the environment contaminating toxic substances which have been previously retained during operation of the laboratory extraction hood (1) for the analysis of samples or objects, and c) extracting the filter unit (9) from the laboratory extraction hood (1). A kit (2) for actuating the aforesaid method is also disclosed, and a laboratory extraction hood (1) comprising this kit (2).
