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 Chapter 2.1
"Proper use", page 7 and any application that does not comply with the technical
specifications (see Chapter 3.5 "Technical data", page 12) 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.
