Operation
Spin only balanced loads. Use only Mylar Coatedor plastic capillary tubes. Make sure that capillary tubes are placed
opposite each other. Proper sample balancing will improve sample separation and will extendthe life of the centri-
fuge. Out-of-balance loads may damage the centrifuge.
Be certain to follow the instructions on the included vial of capillary tubes when drawing the specimen and sealing
the tube. IMPORTANT: The tubes must be sealed on the dry end – the end opposite from the one in which the speci-
men was drawn. Improper technique can result in the sealant and specimen leaking out into the tube shields during
centrifugation. Should this happens, the tube shields need to be replaced or removed from the rotor and thoroughly
cleaned with hot soapy water and then allowed to dry completely. Failure to do this can cause leakage and/or tube
breakage during future runs.
Set timer for 5minutes. Unit will begin spinning at full speed (10,000 rpm).
After unit has stopped, carefully remove the capillary tubes and hold vertically.
Place the reader card directly behind the tube, and align the top and bottom of the fluid with the 0 and100 lines.
The separation line should be read on the graph at the point of the separation.
Note: The separation line will be at an angle, therefore you must read the midpoint of the angle for an accurate
percentage.
