How a "dry powder" nanoworkshop works?
Various milling workshops produce nano-objects in the form of micronic powders on the NANOMIL platform. If only a fraction of the powders handled is nanoscale, the operations require confinement. All equipment (glove box, sorbonne, mills) must have external extractions with HEPA H14 filters ensuring control of environmental emissions. Apart from the risk of dispersion, the risk of explosive atmospheres linked to the flammability of certain powders is to be considered. Strict maintenance and waste management procedures must be applied.
Main cleaning in glovebox.
Utensils liquid cleaning in a fume chamber.
Any component coming into direct contact with nanopowder must be cleaned on site. The main cleaning is carried out in the glovebox using towelettes impregnated with solvent. Before being stored away the utensils are cleaned with liquid in a fume chamber.
