Labnet Prism Air-Cooled Microcentrifuge (C2500) - Manual (Page 11)

4. 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.
4.1 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.
4.2 Closing the lid
Close the centrifuge lid. The Prism has a lid lock that activates only when a run is
started.
4.3 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.
4.4 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.
