When working or in a hospital or a laboratory, a tool that is used often to liquid is called a pipette. This is a larger version of the medicine dropper and works on the same principle of creating a vacuum to draw fluid that is released when pressed.

To ensure accuracy at all times, this instrument must be calibrated. This depends on four main factors, namely: the ability of the people in the lab, and the addressthese devices, the type of fluid is put into the pipette and the type of work that is used when the facility.

In most cases, these instruments are calibrated every 6 months, but companies that are involved with food or drugs, are quarterly or every 3 months is required. Schools that have the behavior of chemical classes can do it, but every year in research and forensic medicine, where there is a lot of tests done this month.

Like calibratedcalibrated? This is usually done by gravimetric analysis. Every tool tested by the omission of distilled water in a jar. Each pipette should be able to be the same volume to the required weight acting at the National Institute for Safety and NIST or release.

An expensive way to calibrate the pipettes will be used with the method in which the color meter and colored water is dispensed. A spectrophotometer is used to measure the weight, which then decides whetherSome adjustments must be made in instruments.

The way to do the calibration, in reality depends on selected contractor. The rigid, which certifies that the site is on an international level if ISO / IEC 17025, the highest so far.

This means that the staff of the structure are well trained and practice the latest techniques to implement anything in the lab. These companies not only private, but in other places that are running, notby the government as the Centers for Disease Control or CDC, and the enforcement by the prosecuting authorities. This is to ensure the safety of workers and the people.

So if the person needs to make the blood or any other evidence, is a good idea in a place that has these rules in place to achieve an objective and accurate results to be done.
