4 The principle of centrifugal machine manual need know
Centrifugal machine is one of the popular device in the laboratory equipment however many professionals are also not well understood and adequately the principles Manual centrifuges. Instead of opening the lid the centrifugal machine, for your template and click the button “turn on”.
You need to know the basic principles of safety in the laboratory. Centrifuge operation at high speeds so great centrifugal force so that when used incorrectly can create a serious danger.
1. Read carefully the instructions used centrifuges from the manufacturer
Many different manufacturers of centrifugal machine. Each machine is different and each have specific manuals.
So when you are provided with a centrifugal machine, You should learn the protocol operation and follow exactly or you should follow the instructions of the manufacturer.
2. Grounded and protected centrifugal machine
Set the centrifugal machine in a safe place, not affected by external factors such as, the noise level, vibrating, collisions with other devices.
Centrifuges must also lie on the flat surface, sure to speed the vibrations it produces when it is running is kept to a minimum.
If the machine is excessive vibration, switch off the machine immediately in case of machine malfunction or gets heavy load. In order to avoid damage to the equipment.
3. Sample installation on centrifugal machine rotor
Make sure the load balancing. For example: If you have only a sample, Insert a tube in the other side directly opposite the equivalent load model.
It is important to balance it by mass, instead of simply by volume, as recommended by the tip using centrifuges of Stanford University.
For example, If more dense form of water, you have to compensate by adding volume or density greater than on the tube balance. (It should be remembered: by mass balance)
Make sure the volume of the form to true to require of the rotor volume according to manufacturer specifications. Because if the sample volume is greater than that it also snows there set for air at high speed.
4. Close and open the lid the centrifugal machine
Ensure that the lid is closed properly when you give the form to the. In addition, never be opened when the centrifuge it works, because even if the computer could shut down, the remaining energy can continue to spin the samples at high speed so it can shoot out dangerous.
