BALANCED LOADS
Your centrifuge must contain a balanced load in order to work properly.
To ensure that the load is balanced, keep these rules in mind when
inserting test tube samples:
1. Opposing tube carriers must be identical.
2. Opposing tube carriers must be empty or loaded with an equal number of
equally weighted samples.
3. If an odd number of samples is to be spun, use a water-filled tube to mate
with the unpaired one.
Note: The 755 is designed to detect serious out-of-balance situations and will
safely terminate a run if one is detected. The 755 will cut power to the motor
and wait for the rotor to stop spinning before unlocking. The load should be
balanced before an attempt is made to re-run.
4. When loading tubes into opposing
carriers, the carriers will be balanced
when the tubes are loaded diagonally
from one another. See the illustration
to the right.
Note: When loading tubes that are
longer than 100mm in length, the
maximum capacity is two (2) tubes
per carrier. Place these longer tubes
in the right-hand side of each carrier.
Note: When spinning glass tubes in
the 4-place carrier, it is recommended
that the 0.25” tube cushion (p/n 9150)
be placed in the bottom of the carrier.
