Maximum speed for tubes
Some tubes, such as centrifuge glass tubes, microtubes, culture tubes,
fluoropolymer tubes and especially high-volume tubes can be used in our
rotors, buckets, and adapters at higher speeds than their breaking limit.
NOTE
When using glass vessels, the maximum value of 4,000 x g must not be
exceeded (except special high-strength glass tubes; please refer to the
information provided by the manufacturer).
NOTE
When installing the 500 ml bottles use the supplied supporting rings.
CAUTION
At speeds above 8,000 rpm, there is an increased risk of breakage, in
particular for 250 and 500 ml bottles!
Blood bag systems
• Alle •
All six places on the rotor must be loaded with buckets.
• It is required to fill just two opposite buckets must be filled with one
adapter for blood bags and two blood bag systems each.
• The opposite buckets, including the filled blood bag systems, must have
an equal weight. If the number of blood bags is uneven, a balance
adapter must be used. For taring, several balance weights are
available.
• The blood bags must be put into opposite buckets in a mirror-inverted
way (see figure).
• In both adapter compartments, the main blood bag must be situated
towards the middle. The opposite bucket must be loaded
correspondingly (see figure, item 1).
• When using smaller bag systems or in the case of incompletely filled
blood bags, adapters (e.g. part no. 17750) must be inserted together
with the blood bag systems. This will help to avoid any slipping of the
bags, which could result in an imbalance.
