OPERATION
|
CENTRY™ 103 MINICENTRIFUGE
Preparing the Microtubes
●
Prepare microtubes that are compatible with the rotor in use.
WARNING
Do not use the instrument to centrifuge explosive or flammable samples. It may
cause fatal or serious accidents. The instrument does not provide adequate
protection against explosion or ignition.
Do not use the instrument to centrifuge infectious samples. It may cause a serious
hazard to laboratory personnel. The instrument is not a biohazard safety model.
If there is the need to handle any potentially infectious or radioactive samples, or other
hazardous materials, implement appropriate safety measures.
●
Load the microtubes in the rotor symmetrically. Always ensure that the microtubes
are appropriately balanced, as described in Figures 3 and 4 on page 7 (black circles
indicate different possible tube placement).
NOTICE
Imbalanced loads will significantly reduce the life of the motor and minicentrifuge.
WARNING
In severe cases, imbalances may damage the Minicentrifuge and injure the operator.
CAUTION
Do not overfill microtubes. The sample volume should not exceed 70% of the maximum
allowable volume of the tube in use. The sample may spill during run and damage the
minicentrifuge.
Always use capped microtubes. The sample may spill during run.
Starting and Ending Operation
●
By closing the lid
1
, the rotor instantly starts spinning. After six minutes of spinning,
the rotor will automatically decelerate to a stop.
WARNING
Ensure that there is no foreign material in the rotor or in the chamber before
operating the instrument. It may break a sample during spinning and the broken
pieces may scatter, resulting in a serious accident.
●
For ending the operation, lightly press down on the lid
1
. The rotor will decelerate
and the lid will lift automatically.
●
The operation ends when the rotor is completely stopped, and the sample tubes can be
unloaded.
WARNING
Never open the lid while the rotor is spinning. Accidental contact with the spinning
rotor may cause a serious injury.
Using Batteries
The instrument can be operated using battery power when there is no power supply available.
●
Install four AA alkaline batteries of the same brand in the battery compartment
7
.
(Refer to Figure 1 on the first page.)
●
The AC adapter is given first priority if connected.
WARNING
Do not mix batteries by age or by brand type. The battery may cause heating, leakage, or
explosion and could result in damage to the instrument or personal injury.
When leaving the instrument out of use for a long period of time, be sure to remove the
batteries for safety. The battery may cause leakage and could result in damage to the
instrument or personal injury.
Do not attempt to replace the batteries immediately after use, touching them could result in burns.
