7.0 Operation

ATTENTION: Never attempt to operate the centrifuge with rotors or adapters that show signs of
corrosion or mechanical damage. Never centrifuge strongly corrosive materials that may damage the
rotors, accessories, or bowl of the unit.

7.1 Attaching Rotor Lid

After the rotor has been properly secured and loaded, attach the rotor lid to the rotor. Always use the
rotor lid for safety and to allow the rotor to reach proper speed. Make sure that the rotor lid snaps
securely into place, by pressing down on center catch.

7.2 Closing the Lid

Close the centrifuge lid. The Prism™ Microcentrifuge has a lid lock that activates only when a run is started.

7.3 Lid Release

The lid will remain locked during a centrifuge run. Once the run has been completed and the rotor has
come to a stop, a beep will indicate the end of a run, and the lid will unlock automatically.
WARNING: Do not attempt to open the lid of any centrifuge until the rotor has come to a complete stop.
In the event of a power failure or malfunction, it may be necessary to open the lid manually.
1. Disconnect the power cord from the wall socket.
2. Remove the plastic plug, located on the left side of the unit.
3. Pull the wire (attached to the plug) to open the lid lock manually.

7.4 Lid Lock

The centrifuge can be started only with the lid securely closed. When a run is started, the lid lock
automatically activates. Do not attempt to open the lid during a centrifuge run. At the end of the
run, the lid will automatically unlock. Never attempt to override the lid lock mechanism. Doing so is
dangerous and could damage the centrifuge.
