What is Centrifuge ???

Centrifuge is designed to use thecentrifugal force genereted in

rotational movement toseparate the constitutive

elements of a mixture

Function of Centrifuge ...

Use to separating solidssuspended to separated component ofblood

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.


5/13

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%.


6/13

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.


7/13

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.

clasification

General purpose centrifuge

The model is usually a tabletop

Designed for separation of urine samples.

Micro Centrifuge

Microtubes volume range 0,5-2,0 mL

rotated special microtubes at high speed

Speciality Centrifuge

uses for specific purpose

kind ; microhematocrit centrifuge and blood bankcentrifuge

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

Routine Maintenance

Routine maintenance required by a centrifuge dependson multiple factors, such as :

The incorporated technology

Usage intensityTraining of users

Quality of the electrical feed and environmentalconditions.
