Characteristics of the Sorvall Legend XT/XTRThe Sorvall Legend XT/XTR is an in-vitro diagnostics device according to the In-Vitro Diagnostics Directive 98/79/EC.

Several rotors with a wide range of tubes can be used.

The set speed is reached within seconds. The maintenance-free induction motor ensures quiet and low-vibration operation even at high speeds, and guarantees a very long lifetime.

The user-friendly control panel makes it easy to pre-set the speed, RCF value, running time, temperature, and running profile (acceleration and braking curves). You can choose between the display of speed and RCF or the entry mode.

These settings can be changed even while the centrifuge is running.

With the help of the PULSE key , you can also centrifuge a sample for just a few seconds, if called for.

The Sorvall Legend XT/XTR is equipped with various safety features:

• The housing and rotor chamber consist of steel plate, the interior of armour steel, while the front panel is made of high-impact resistant plastic.

• The lid is equipped with a view port and a lock.

• The lid of the centrifuge can only be opened while the centrifuge is switched on and the rotor has come to a complete stop. The centrifuge cannot be started until the lid has been closed properly.

• The integrated rotor detection systems ensures that no inadmissible speed settings can be preselected.

• Electronic imbalance recognition

• Lid emergency release: For emergencies only, e.g. during power failures (see “Mechanische Notentriegelung des Deckels” auf Seite 7-2)

4 OperationRotor Installation

Thermo Scientific Sorvall Legend XT 4-3

The centrifuge is equipped with an AutoLockTM locking system.This system is used to automatically lock the rotor to the centrifuge spindle. The rotor does not have to be bolted on to the centrifuge spindle.

Proceed as follows:

1. Open the lid of the centrifuge and if necessary remove any dust, foreign objects or residue from the chamber. AutoLockTM and o-ring must be clean and undamaged.

Figure 4-1. AutoLockTM

2. Place the rotor over the centrifuge spindle and let it slide slowly down the centrifuge spindle.The rotor clicks automatically into place.

3. Check if the rotor is properly installed by lifting it slightly on the handle. If the rotor can be pulled up, then it must be reclamped to the centrifuge spindle.

CAUTION Unapproved or incorrectly combined accessories can cause serious damage to the centrifuge.

CAUTION Do not force the rotor onto the centrifuge spindle.If the rotor is very light, then it may be necessary to press it onto the centrifuge spindle with a bit of pressure.

WARNING If the rotor cannot be properly locked in place after several attempts, then the AutoLockTM is defective and you are not permitted to operate the rotor.Check for any damage to the rotor: Damaged rotors must not be used.Keep the centrifuge spindle area of the rotor clear of objects.

CAUTION Check that the rotor is properly locked on the centrifuge spindle before each use by pulling it at its handle.

2. Enter the desired value using the numeric pad. The digits show in sequential order.

3. Confirm your entry by pressing ENTER .Your entry will be automatically confirmed if you do not press any key for 5 seconds.

Running time preselection

1. Press the TIME key in order to open the runtime selection menu. The display shows the message "Set Time".Enter the desired runtime in hh.mm

Note If an extremely low RCF value has been selected, it will be corrected automatically if the resulting speed is less than 300 rpm. This is because 300 rpm is the lowest selectable speed.

Explanation of RCF Value

The relative centrifugal force is given as a multiple of the force of gravity g. It is a unitless numerical value which is used to compare the separation or sedimentation capacity of various devices, since it is independent of the type of device. Only the centrifuging radius and the speed come into play in it:

r = centrifuging radius in cm

n = Rotational speed in rpm

The maximum RCF value is related to the maximum radius of the tube opening.

Remember that this value is reduced depending on the tubes and adapters used.

This can be accounted for in the calculation above if required.

Mechanical Emergency Door ReleaseDuring a power failure, you will not be able to open the centrifuge lid with the regular electric lid release. A mechanical override is provided to allow sample recovery in the case of an emergency. However, this should be used only in emergencies and after the rotor has come to a complete stop.

Always wait a few minutes until the rotor has come to a stop without braking. The brake does not work when there is no current. The braking process lasts much longer than usual.

Proceed as follows:

1. Make sure the rotor has stopped (view port in the lid).

2. Pull out the power supply plug.

3. On the back of the housing are two black plastic plugs which you can pry out of the back plate with a screwdriver or a knife. Pull the release cord attached to it at the same time to trigger the mechanical lid release. The lid will open and the samples can be removed.
