Technical information

Centrifuge Standard Operating Procedure 15
0 RPM can be programmed for 1-10 minutes), or “OFF” (no brake is used,
and the rotor can take up to 1 hour to coast to a stop). Press “Enter”;
12.Press “ENTER” , followed by “START”;
13.Stay with the centrifuge until full speed is attained. If you sense that the
centrifuge is not running smoothly indicated by abnormal vibration,
whining, or grinding noises, abort the run immediately and recheck the
rotor lid and balance. Report all irresolvable problems to the
Instrumentation Technician.
14.The run will finish when the required “TIME” parameter is met, or when
“STOP” is pressed. Do not attempt to open the lid until the centrifuge has
come to a complete stop.
15.When finished, turn off the centrifuge and clean the chamber and rotor as
directed in Section 6.3.
6.3 After Completing a Run
1. Accurately record the centrifuge/rotor use in the logbook provided. This
information is essential for rotor down rating and centrifuge servicing;
2. Ensure the cleanliness of the rotor and centrifuge;
a. Any condensate or spills inside of the centrifuge chamber must be
cleaned with a mild detergent and wiped dry with a sponge or paper
towel (cleaning materials located in the cupboard beside the
centrifuge).
b. Metal rotors in contact with moisture for extended periods of time
will corrode and become useless. It is very important that the rotor
is left clean and dry after use. Dry the rotor thoroughly.
i. If spilled material is left in the rotor, it could imbalance the
rotor on the next run, spread material throughout the
centrifuge, cause a serious rotor failure, and cause the rotor
itself to corrode.
ii. If a spill occurred, rotors should be cleaned with mild soap and
water (no abrasives) and an all-plastic rotor-cleaning brush
(any metal will scratching the rotor). These items are available
in the cupboard beside the centrifuge.
iii. After the rotor has been cleaned and well rinsed with DI
water, ensure that it has dried completely (upside down or
with a soft sponge or paper towel) before storing in the cold
room.
3. Rotors, lids, and canisters must be stored upside down in the cold room (lids
and caps should be removed).
If you had any problems or concerns regarding the operation of the centrifuge,
please contact the Instrumentation Technician immediately (SR314A, x2361).
