When working either in the clinic or in the laboratory, a very common instrument used to carry liquids called pipette.
It is a larger version of the pipette medicine and works on the same principle of creating a vacuum to draw fluid, which is released when it is pressed.
Pressure and Vacuum Equipment tool is very important to ensure accuracy at any time. It depends on four important factors namely; the skills of those who work in laboratories as well as handling the equipment, the type of fluid that is placed into the pipette and the type of work in which the tool is used.
How pipette calibrated? This is usually done through a gravimetric analysis. Each experienced a testing instrument by spending distilled water into the ship.
The more expensive way to calibrate the pipette is the colorimetric method where water is used and shared. A spectrophotometer was used to measure the weight, which can later determine whether adjustments should be made in the instrument.
The type of calibration that should be done will depend on the chosen contractor. The most rigid stating that the place is up to international standards is when it is ISO / IEC 17025, which is the highest so far.
This means that well-trained personnel in facilities and practicing the most advanced techniques while doing anything in the laboratory.
