Safety
Risks for the samples
l Damaged tubes must not be used.
l Use only liquids and sample containers indicated in this manual. Buffers and tubes different
from those indicated in this manual are not suitable and should not be used.
l Handle samples and closed holder with samples inside with care to avoid creating bubbles
and nullifying the centrifuge effect.
l Do not process samples with bubbles. In case of bubbles, the output sample volume is not
guaranteed.
l For the supernatant to be trapped correctly in the cap, the input sample volume must not
exceed 200 µl.
l Do not use the instrument and its components if not intact.
l Do not apply labels on the tube containing the sample.
l Check the presence of the holder clips. If they are missing, do not use the holder.
l To guarantee correct sample processing, keep the closed holder perpendicular to the plane
(see "Position the closed holder" on page21).
l Do not process samples having a density higher than 1.2 g/mL.
l Use the swing bucket centrifuge only when prescribed. Do not use fixed angle centrifuge.
l Do not use accessories whose maximum service life has been exceeded.
l If unusual noise comes from the instrument, the instrument must be immediately stopped (see
"Stop the volume reduction process" on page31).
