2 Safety
2.1 Proper use
The device has been designed and built for laboratories.
The ultrasonic nozzle together with the ultrasonic controller are designed for spray
drying purposes using the BUCHI Mini Spray Dryer B-290 and its subsystems.
The ultrasonic nozzle together with the ultrasonic controller are designed to atom-
ize liquids with viscosities lower or equal to 50 cps.
2.2 Use other than that intended
Use of any kind other than that described in the section Proper use Chapter2.1
"Proper use", page7 and any application that does not comply with the technical
specifications (see Chapter3.5 "Technical data", page12) constitutes use other
than that intended.
In particular, the following applications are not permissible:
Use of the instrument with non-BUCHI products nor with any other BUCHI model
than the Mini Spray Dryer B-290.
Use of the instrument in an environment with a potential risk of explosion or areas
which require explosion-safe apparatus.
Use of the instrument for processing substances outside of research and develop-
ment.
Use of the instrument for food, pharmacy and cosmetic products without appropri-
ate cleaning.
Use of the instrument without an appropriate leading away exhaust gas from the
working area.
Use of gases with unknown chemical composition.
Use of the instrument with organic solvents (> 20 %) without safety lamella curtain
and Inert Loop B-295.
Use of the instrument with organic solvents (> 20 %) in open mode.
Production and processing of substances that can lead to spontaneous reactions,
such as explosives, metal hydrides or solvents that can form peroxides.
Use of the instrument with samples which produce oxygen during the processing.
Use of the instrument with toxic substances without appropriate safety measures.
Use of the instrument with biohazardous materials such as viruses or bacteria.
Use of the instrument with samples which can block the feed channel of the ultra-
sonic nozzle.
Use of the instrument with substances which might explode or ignite due to the
processing and the selected parameters.
Use of the instrument with corrosive samples other than the Mini Spray Dryer
B-290 ACID.
Use of the instrument with corrosive samples in closed mode.
2.3 Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater
dangers.
The device may only be operated by suitably qualified laboratory staff.
These operating instructions are aimed at the following target groups:

3 Product description
3.1 Description of function
The ultrasonic nozzle with the ultrasonic controller are built to be used as liquid atom-
izer in the spray drying process with the Mini Spray Dryer B-290 and its subsystems.
An ultrasonic atomizing nozzle is a device that vibrates at frequencies beyond human
hearing (>20 kHz). The vibration on the atomizing surface of the nozzle produces a
low velocity spray by breaking up a liquid feed into a spray of droplets. This phenome-
non is the result of the decay of an unstable capillary wave that develops in the liquid.
The spray velocity is typically low with 18-36 cm/s as compared to 10-20 m/s for pres-
sure atomizing nozzles. The ultrasonic controller provides the high frequency electri-
cal energy required to operate the ultrasonic atomizer nozzle.
Three modes are available:
Mode Solvent composition
Open mode up to 20 % organic solvent
Closed mode with
B-295
between 80 % - 100 % organic solvent
Closed mode with
B-295 and B-296
between 20 % - 80 % organic solvent
