Volume Measurement and Calibration UAE
• Essential in fields like chemistry, health, biology, pharmacy, and fuel depot.
• Reliable and accurate volume quantities measured using volume instruments are crucial.
• Calibration of volume instruments using correct methods is necessary to reduce errors in liquid handling.
• Volume instruments can be calibrated by filling or emptying, comparing two volumes, or by weighing the quantity of a suitable liquid.
• Weighing is the most important step in gravimetric calibration, influenced by factors such as the resolution and sensitivity of the balance, calibration of the balance, and the class and density of the reference weights used.
• Ambient conditions such as air temperature, humidity, and barometric pressure influence gravimetric measurement.
• Calibration must be carried out after the temperature between the calibration object and the environment has been equalized.
• The volumetric method applies to calibrating any size of volume measures for which standard pipets of comparable volume are available.
• Calibration of flask involves an initial wet-down using the correct drain procedure, then nearly filled with water delivered from a calibrated pipet.
• Standard and equipment for calibration include calibrated standard volume measures, calibrated burette(s), calibrated thermometers, meniscus reading device, and stopwatch or other suitable timing device.
