Isolation for reactor for deposition of films onto particles

A deposition system comprising:

• an isolator comprising a glovebox;
• a detachable transfer container attachable to the isolator by a rapid transfer port;
• and
• a reactor for coating particles, the reactor including a rotatable reactor assembly positioned within the isolator and reachable with gloves of the glovebox and including:
• a reactor drum configured to hold a plurality of particles to be coated,
• an inlet tube including an inlet flange, and
• an outlet tube including an outlet flange, and
• wherein the reactor drum is configured to be detached from the inlet flange and the outlet flange by connectors securing the inlet flange and the outlet flange to the reactor drum by an operator using the gloves while the reactor drum remains within the isolator.
