Operating Instructions
Opening and Closing the Cover
The centrifuge’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 centrifuge 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.
Installing the Rotor
All rotor bottoms fit over a rubber O-Ring on the rotor-holder. The
figure on the left shows a rotor, cross section, in place on the rotor
holder. As the rotor turns, the O-Ring is moved outward by
centrifugal force enhancing the frictional coupling between the
rotor-holder and the rotor.
CAUTION- Do not leave any rotor on the rotor-holder when the StatSpin is not in use
for an extended period of time. Doing so may compress the O-Ring and decrease it’s
ability to hold rotors.
CAUTION- Failure to properly install the rotor may result in damage to the centrifuge
and will void the warranty.
CAUTION- If rotor is left in place between runs, be certain to “bottom” the rotor on the
rotor-holder before spinning another sample. Failure to properly “seat” the rotor each
time may result in the rotor becoming loose during centrifugation.
CAUTION- The RT12 and RM02 tube rotors must be balanced before operation. If
only one sample is being processed, a second sample can serve as the balance tube
or use a similar tube filled with water as a balance.
