CHAPTER 3
Operating Instructions
Opening and Closing the Cover
To close the lid, firmly apply pressure on the cover directly above the latch until the gasket
compresses completely and the latch engages with the cover. The electrically operated
cover interlock mechanism prevents operation until the cover is completely closed and
locked, and prevents the cover from being opened while the centrifuge is in operation.
When the cover is completely closed and locked, an operating cycle can be initiated.
The centrifuge has a manually operated latch that holds the cover down after spinning is
complete. The interlock is automatically released at the end of the operating cycle or by
pushing the
Stop or Open button. Squeeze the black latch pieces together to open cover.
Cover Interlock By-pass
Caution
The cover interlock bypass is for emergency use only. Disconnect the power cord of
the external power supply from the electrical outlet and ensure the rotor has come to
a complete stop before using the interlock bypass. If the equipment is not used
correctly, safety can be impaired.
To release the electronically operated cover interlock mechanism, insert the straightened
end of a large paper clip or similar object into the small hole in the center of the front
membrane panel. If you press the
Stop or Open button and the cover does not release, push
the lock lever inward about one inch (25mm) to release the interlock mechanism.
Removing and Installing the Rotor
The StatSpin Express 2 is shipped with the rotor installed. To prevent possible damage to
the motor mount of the centrifuge, remove the rotor whenever the centrifuge is shipped to
another location.
Caution
Inspect rotor on a routine basis. Rotor lifespan depends on usage. Inspect rotors for
cracks and replace the rotors immediately when any crack or visible wear occurs.
1
Remove the tube inserts from the rotor.
2
Remove the rotor, retaining nut, and washer from the rotor holder using a 7/16" nut
driver.
3
Gently rock the rotor back and forth until the mounting pins on the rotor holder release.
4
Remove the rotor.
