WARNING
Do not use the ultracentrifuge in the vicinity
of flammable liquids or vapors, and do not
run such materials in the instrument. Do not
lean on the instrument or place items on it
while it is operating.
STARTING THE RUN
1. Connect the power cord and turn the air supply on.
!
CAUTION
Never operate the ultracentrifuge without a
rotor cap or lid installed on the rotor.
2. Load the rotor and secure the rotor lid or cap as described in the
applicable rotor manual. Tubes should be symmetrically loaded in
a fixed angle rotor; rotor liners should be full and evenly seated in
their rotor base.
➠
NOTE
If you are using an Airfuge with the digital
speed readout accessory installed, use a flat
black marker to color half of the rotor lid or cap
flat black. If the black surface is shiny, inaccu-
rate speed readings will be displayed.
3. Lightly touch the brake pin to be sure it operates freely.
4. Check the stator pad; it must be clean and in good condition.
A worn stator pad is smooth and shiny on the inside surface
(see Figure 3-1). Replace a worn stator pad.
➠
NOTE
Stator pads—especially the white circles on the
bottom—should be kept clean with alcohol.
