2-2-4 Rotor Adapter/Disk

2-2-4 Rotor Adapter/Disk
There are three types of adapters for rotors : RLM adapter, optical adapter, and optical disk.
(1) RLM adapter
This type of adapter has a memory to manage the rotor life.The rotor type (that includes the
information about the maximum permitted speed of the rotor), serial number, total number of
runs,and accumulated run time are recorded in this memory.Rotors with RLM adapters are
termed RLM rotors (automatically managed rotors.) (See Fig. 2-2-3).
WARNING: Use a RLM rotor manufactured by Hitachi Koki with only Hitachi ultracentrifuges.
(2) Optical adapter
This type of adapter has alternating black and white bands around its circumference.
The number of bands corresponds to the maximum permitted speed of the rotor. Rotors with
optical adapters are termed rotors with optical adapters (See Fig.2-2-4 (a)).
(3) Optical disk
This type of disk has alternating black and white sectors on its disk.
The number of bands corresponds to the maximum permitted speed of the rotor. Rotors with
optical disks are termed rotors with optical disks (See Fig.2-2-4 (b)).

The rotor with an RLM adapter or an optical disk is available to this centrifuge.
CAUTION: R28SA,RPS27-2,RPS27-3,RPS25,RPS25-2,
RPS25-3rotor,etc. are not available to this centrifuge.
As shown in the right figure, each of these rotors
includes the pin portion(the detector to exceeding
the speed).
Never use these rotors,otherwise the pin portion
may touch the bottom of the rotor chamber when
the rotor is rotating,and it may cause the rotor
chamber damage.
After many years of use, there will be inevitably some corrosion or stress corrosion. At
some points, the combination of such damage and metal fatigue could make the rotor
vulnerable to a failure.
Although a rotor may appear to be in a good condition, you should follow the rotor
retirement recommendation (see the rotor instruction manual).
Failure to do so can cause the centrifuge to become damaged.
