Operating Instructions
Opening and Closing the Cover
The system’s electrically operated cover interlock mechanism prevents operation until the cover is
completely closed and latched, and prevents the cover from being opened while the rotor is turning.
When the cover is completely closed and locked an operating cycle can be initiated.
The system is also equipped with 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/open button. Squeeze the black latch pieces together to open cover.
Cover Interlock By-pass
The electronically operated cover interlock mechanism can be released manually by inserting the
straightened end of a large paper clip or similar object into the small hole in the center of the front
membrane panel. Manually push the lock lever inward about one inch (25mm) to release the
interlock mechanism if the stop/open button does not release the cover.
CAUTION - The cover interlock bypass is designed for emergency use only. If the
equipment is not used properly, safety may be compromised.
Removing and Installing the Rotor
The Express 2 is shipped with the rotor installed. To prevent possible damage to the centrifuge’s
motor mount, it is important to remove the rotor whenever the centrifuge is moved or shipped to
another location.
CAUTION- The rotor (RTX4) has a finite lifespan that is dependant on usage. Cracks
or swelling are signs of fatigue, replace immediately.
1. Remove the tube inserts from the rotor.
2. Remove rotor, locking nut and washer from the rotor holder using 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.
To re-install rotor:
1. Remove the tube inserts from rotor. Place rotor on rotor holder, ensuring the two mounting pins
on the rotor holder are aligned with two of the four small holes near the center of the rotor.
2. Gently rock the rotor back and forth to ensure the rotor seats properly on the rotor holder.
3. Install washer, then nut and secure the rotor by tightening the nut with the 7/16” nut driver
provided.
4. Re-install the tube inserts into the rotor cavities. The centrifuge is now ready for use.
CAUTION- Failure to properly install the rotor may result in damage to the centrifuge
and will void the warranty.
