6.2 Operation with the Inert Loop B­295
The Mini Spray Dryer B­290 with the ultrasonic nozzle and the Inert Loop B­295
is operated in the same way as described in the Mini Spray Dryer B­290 opera­
tion manual section 6.7. As the inert gas (N
2
) is not introduced into the system
by the ultrasonic nozzle, an Inert Loop Adapter (11060492) is needed to inject
the inert gas into the system.
