High-speed centrifuges
are equipped in many laboratories. Recently, there has been frequent news of
centrifuge injury incidents. The safety hazards of laboratories are still a
concern for everyone. So what should be paid attention to when using high-speed
centrifuges?
1. When the high-speed centrifuge is
pre-cooling, the lid of the centrifuge must be closed. After the centrifugation
is completed, the rotor needs to be taken out and placed on the laboratory
bench to control the water inside. The lid should also be opened to dry.
2. When using a high-speed centrifuge for
ultracentrifugation, the centrifuge
tube must be filled with liquid samples, and the vacuum needs to be
removed during ultrafiltration centrifugation, which can effectively avoid the
deformation of the centrifuge tube. Be sure to ensure that the cap of the
centrifuge tube is tightly closed to prevent liquid leakage and affecting the
work of the sensor.
3. During pre-cooling, the rotor, and cover
of the centrifuge can be removed and placed on the test bench, and must not be
placed on the rotor without fixing it, which may easily lead to misoperation
and safety accidents!
4. When putting on the centrifuge rotor
cover, be sure to use tools to tighten the rotor, and then start the centrifuge
button after confirming the safety. Do not allow the cover to be loose. Before
running, confirm whether there is a hidden danger of foreign objects in the vicinity.
If necessary, remove the hidden danger before starting.
5. In the centrifugation experiment, the
high-speed centrifuge needs to be placed on a stable and horizontal test bench
to reduce the tilt of the body. In this way, the sample and the instrument are
in a relatively balanced working state and at a safe distance during high-speed
rotation. At the same time, the internal friction of the centrifuge is reduced
and the service life is prolonged.
6. When using the high-speed centrifuge,
the operator needs to take care of the whole process. In case of emergency, it
is necessary to press the stop button urgently to perform deceleration and stop
operations.
