5.2.3.2 Installation of the Microhematocrite Rotor
•
Lower the microhematocrite rotor with its central bore straight down onto the
motor shaft.
•
Tighten the rotor tie-down screw clockwise with the supplied rotor wrench. In
doing so, hold the microhematocrite rotor with your left hand and tilt it slightly,
if necessary, in order to prevent the motor shaft from slipping through.
•
Check the rotor for a correct and tight fit.
•
Please consider the maximum permissible gravitational field of 12,000 x
g. An excess gravitational field will result in an increased risk of glass
breakage!
Operation:
•
Fill the capillary tubes with blood and seal them at one end with putty or by
fusion.
•
Place the capillary tubes into the recesses of the rotor with the sealed end
against the rubber ring. Ensure that the capillary tubes fit tightly against the
rubber ring. The opposite places must be loaded.
•
Screw on the rotor cover.
•
Close the centrifuge lid.
•
Enter the following parameters: gravitational field RCF max. 12,000 x g, time
5 min
•
Start the centrifuge.
•
Open the centrifuge lid and rotor cover when the set time has elapsed.
Evaluation:
•
Put the reader onto the rotor.
•
Turn the reader and perform a fine adjustment with the aid of the central
eccentric mechanism in order to localize the O-point and the maximum liquid
point in the capillary tubes. You can now read the percentage value.
•
Remove the capillary tubes. Some of the tubes can also be evaluated with
the reader outside of the rotor (see the instructions for use on the back of the
reader).
