Centrifuge failure solution and operation use

Centrifugal separation technology has also undergone several generations of replacement, from medical centrifuges, low-speed refrigerated centrifuges, high-speed centrifuges to high-speed refrigerated centrifuges, super-capacity refrigerated centrifuges, ultra-centrifuges, ultra-refrigerated centrifuges, intelligent high-speed refrigerated centrifuges
.

Question 1: What should be paid attention to in the placement of centrifuges? A: Centrifuges are generally placed in a dry place
, away from direct sunlight.

The heat dissipation of the centrifuge is relatively large, do not pile up debris around, and the surrounding is at least 10cm or more
from the walls, baffles and other non-breathable and poor heat dissipation items.

At the same time, the centrifuge should be placed in a separate room as much as possible, and organic reagents and flammable products
should not be placed around.

Question 2: What maintenance should the centrifuge pay attention to, which can extend the life? Answer: After each use, the centrifuge lid should be opened so that the heat or water vapor evaporates naturally, such as the previous use of low-temperature centrifugation, there may be ice, then wait for the ice to melt, scrub it with dry cotton gauze in time, and then cover the lid
when there is no obvious water vapor.

If the centrifuge rotor can be replaced, then each rotor should be removed in time after use, scrubbed with clean, dry medical gauze, placed upside down, and never scraped
with sharp objects.

The aluminum rotor should be cleaned frequently, and the centrifuge should be often maintained and overhauled, and the operator should cut off the power supply
when leaving.

First-time users should consult people who have used it before or refer to the instruction manual, and do not use
it blindly.

Question 3: What should we pay attention to when doing specific operations? A: When we use it, we must pay attention to
all aspects.

After selecting the rotor and setting the parameters, observe the centrifuge for a while, and wait until it reaches a high speed and runs stably before leaving
.

If you hear an abnormal sound or smell something during operation, you should immediately take the brakes, press the "Stop" button, and if necessary, cut off the power
supply.

Centrifuge tubes should be placed symmetrically, and the corresponding centrifuge tubes should be as equal in
weight as possible.

During the operation of the instrument, it is forbidden to open the centrifuge lid! At the same time, all personnel in the laboratory develop good registration habits, and can know who has used it before and the condition of the instrument before; The second is to know the number of times the centrifuge is used, so as to know whether it needs to be repaired or replaced
.

Question 4: What are the common accidents of centrifuges? Answer: Due to the high frequency of use of centrifuges, so the machine damage and accident frequency is higher, the main reason is or the experimental personnel improper operation caused, common problems are: the cover can not be opened, the centrifuge tube can not be taken out, the centrifuge does not work after pressing the button, the more serious problems are uneven pressure on the shaft leading to bending, the motor burned out, the horizontal bucket is thrown out, more serious accidents and even injuries and so on
