6.2.2.3
Adapters
In order to ensure easy handling, even if vessels of various sizes are used,
carrier systems were developed.
• Load the opposite adapters with the same number of vessels and with
the same weights in order to avoid imbalance.
• If all of the compartments of a carrier are not used, the buckets must be
loaded evenly. Loading the edges of a bucket only is not permissible.
6.2.2.4
Vessels
General
• Load the vessels outside of the centrifuge. Liquids in the bores of the
rotor cause corrosion.
• Fill the vessels carefully and arrange them according to their weight.
Imbalances result in the excessive wear of the bearings.
• Follow the safety instructions and hazard warnings (see chapter 3 -
Glass vessels
• When using glass vessels, the maximum value of 4,000 x g must not be
exceeded (except special high-strength glass vessels; please refer to
the information provided by the manufacturer).
• When inserting 100 ml glass tubes (part no. 15100) into the buckets, a
rubber cushion (part no. 16051) is mandatory.
CAUTION
If the glass tubes (part no. 15100) are used without a rubber cushion, they
may break!
