Rotor - Hitachi CR22N Instruction Manual

2-1-2 ROTOR

2-1-2 ROTOR
WARNING：1.Never use any rotor, bucket, assembly, etc. that is not designated for the centrifuge by
Hitachi Koki.
2.Do not use corroded, scratched or cracked rotor, buckets and assemblies. Check that the
rotor, buckets and assemblies are free of such abnormalities before operation.
3.Do not exceed the maximum rated speed of the rotor or buckets in use.
4.Be sure to set all the buckets of the same serial number.
5.The rotor speed should be limited depending on
the mean density of sample and the sample weight.
Refer to the rotor instruction manual for details.
6.Do not remove the adapter of the inner of the door,
the cover of the left side of the centrifuge and
the caps of the inside of rotor chamber except
using a continuous flow rotor in the CR22N
refrigerated centrifuge.
The CR22N refrigerated centrifuge
does not conform to the CE marking
requirements when using a continuous
flow rotor due to the construction of the rotor.
Do not remove the adapter of the inner of the door, the cover of the left side of the
centrifuge and the caps of the inside of rotor chamber if your centrifuge is
the CR21N refrigerated centrifuge. A continuous flow rotor is not applicable to the
CR21N refrigerated centrifuge.
CAUTION ： 1.Read the rotor instruction manual thoroughly before use.
2.Never use any adapter, tube or bottle that is not designated for the centrifuge by Hitachi
Koki.
3.Mount the rotor cover securely.
4.Do not exceed the allowable imbalance.
5.Be careful that imbalance operation may occur in the following cases. Fill the same
sample in the same tubes/bottles and load them in the buckets that are placed
symmetrically with respect to the drive shaft in the rotor.
• If samples that are equal in volume but different in composition are used, the
•
If samples that are equal in weight but different in volume (density) are used or if the
tubes/bottles are different in inside diameter, material, or shape, there may be
variations in position of center of gravity and such operation may cause imbalance.
6.Be sure to set all the plates and all the plate adapters when using the horizontal rotor.
7.Do not run this centrifuge over the allowable maximum speed of the rotor, buckets, tube, bottle,
tube/bottle cap, and adapters.
maximum speed among them. The allowable maximum speed may be limited depend on
the combination of the tube/bottle, the tube/bottle cap, and the adapter. For the allowable
maximum speed, refer to the rotor instruction manual provided with the rotor. When
using tubes on the market, perform operation under the allowable speed or the
allowable RCF specified by the manufacturer. Otherwise the tubes may be broken
during operation.
8.Although the tubes/bottles are balanced within the allowable range, imbalance alarm
may occur when setting the acceleration rate 8 or less depending on the combination of
the tubes/ bottles and the rotor. Balance them more accurately.
For the specifications of applicable rotors to this centrifuge, refer to the "Applicable rotors to the CR-N
series centrifuge".
precipitation levels may be different by centrifugation and such operation may
increase the level of imbalance.
