What is meant by calibration of the laboratory equipment and why is it necessary?

Answer 1

In a nutshell, calibration is making sure that your error will be as little as possible. It is an adjusting of the equipment so that your measurements can be as precise as possible so that you will get as little error as possible (aka you can be as "right" as possible). If your don't calibrate your equipment, then that means all your measurements are off and your expeiments and data will be incorrect and in effect, invalid. For instance, you have to measure certain ingredients to bake a yummy cake right? Same type of idea. =) Good luck!!!

Answer 2

The collection of accurate chemical data is very important especially in quality control and forensics among others. Since a lot of that data is gathered using laboratory equipment and instrumentation it is very important that they give accurate results. To ensure accuracy the equipment is callibrated against known standards. For example a balance can be calibrated by weighing standards of known mass and comparing them to what the balance says. If it does not correspond to the known mass the balance can be adjusted so that it does. This procedure is known as calibration. Similar procedures are followed for other pieces of laboratory equipment. I hope this helps you out.

Answer 3

The process of determining the performance parameters of an artifact, instrument, or system by comparing it with measurement standards. Adjustment may be a part of a calibration, but not necessarily. A calibration assures that a device or system will produce results which meet or exceed some defined criteria with a specified degree of confidence

Answer 4

Calibration is performing independent measurements on a piece of lab equipment and adjusting settings on it accordingly, such that it gives accurate values.

A number of factors can contribute to a piece of equipment becoming inaccurate, including parts wear ing down, environments changing (altitude, temperature, etc), and often simply the passage of time.

A piece of equipment may stay usable for a long period of time, but as these factors change, calibration becomes necessary.

Answer 5

Let's say you have a scale. In moving, it might be adjusted and no longer properly display the weight. You take a known mass, like a 1 kg mass, and put it on the scale. If the scale does not display 1 kg, you adjust it.

Calibration is important because without it you don't know that you are getting correct measurements.

Answer 6

look on the VWR or Fischer scientific web content. There are in my opinion priced catalog listings. additionally, there are "initiate-up" specials wherein those companies want to be certain an prolonged term courting, so as that they assist you initiate your lab for the 1st time and supply you various loose samples.
