What is Centrifuge ???
Centrifuge is designed to use thecentrifugal force genereted in
rotational movement toseparate the constitutive
elements of a mixture

Calibration of Centrifuge
Calibration is performed by measuring thespeed centrifuges per minute and time.Refrigerated centrifuge in addition to the calibrationon rpm and time also need to calibrate thetemperature.

Calibration of timers
Set centrifuges at a frequently used example5 minutes.
Run the tool and run it in conjunction with
the stopwatch. At the time of centrifuges to stop, turn off
the stopwatch, stopwatchrecord the time indicated.
Repeat several times, calculate the average
The ticker is still acceptable if the deviation of themean value of not more than 10%.

Calibration rpmTachometer mechanical
End of the cable attached to themotor coil inside, while the other end connectedto the meter.
Set centrifuged at certain rpm, then run.
Note the rpm is indicated by a meter on tachometer.
Repeat several times, calculate the average.

Electric tachometer
Place the magnet around the coil, causing a flow ofelectricity whenthe tool is run.
Set centrifuged at certain rpm.
Arising electricity will drive the meter. Note the rpm is indicated by a meter on
the tachometer.
Repeat several times, calculate the average.

Operation Principles
The centrifuge uses centrifugal force (the forcegenerated when an object rotates around a singlepoint).
Centrifuges represent a practical application ofNewtons law of motion.

How to use of centrifuge???
Before starting the centrifuge,make sure that thelid during the last centrifuge
Check the cleanliness of room,clean up all spillsimmediately.
Always doing universal precautions (biohazard)
Balance the load centrifuge before use
Use the shield and the right tube
Play a sample with a lid attached
Use spesial tube to the centrifuge
