Nanomil

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.

How to guarantee total confinement?

The confinement is obtained by means of a double barrier at each activity phase:

  • storage and transportation: polyethylene jacket and ADR-approved polyethylene drum,
  • grinder and glovebox: sealed walls + vacuum,
  • grinder / glovebox transfer: sealed pipes + vacuum,
  • waste management: polyethylene jacket and ADR-approved polyethylene drum.
