5. Before operating the centrifuge again, replace the release button.
NOTE: Do not attempt to operate the release while the rotor is spinning.
To Calculate Separation Acceleration & RPM:
RCF = 11.18 x r x (n/1000) 2
Where:
r = radius in cm
n = speed in rpm
The effective centrifugal radius of the 12 x 1.5ml rotor is 6.3 cm.

Centrifuge Rotor Usage Guide

The VWR 1207 rotors are intended for the sole purpose of spinning samples in the VWR 1207
microcentrifuge.
Use of this product in a manner not specified by the manufacturer may impair or negate
any safety protection provided by the maker.
Good laboratory practice includes observing and following the safety precautions listed in this
guide.
As with any centrifuge, always wear shatterproof, full coverage, wraparound eye
protection and laboratory clothing with long sleeves. Observe all appropriate safety
precautions for the materials in use as detailed by Material Safety Data Sheets.
Rotor Maintenance
Visually inspect the rotor for mechanical or chemical damage prior to each use. Do not use the
rotor if any damage or change is evident. Clean any spills immediately.
Routinely perform mechanical and chemical inspections as follows:
• Check the web area for cracks and crazing.
• Check the rotor underside, including hub area for cracks and crazing.
• Check the outer rim of the rotor. The rotor is comprised of two pieces which have been
ultrasonically welded together; any movement felt between the bottom and top pieces
indicates that a weld has been broken, rendering the rotor unsafe.
- Chemical damage appears as discoloration, crazing, granulation, peeling or similar
deterioration of the finish.
- Hidden mechanical damage may be detected by an increase in noise or vibration
during a spin. If noise level increases, stop use immediately.
If any such changes are apparent, discontinue use immediately.
