Five Key Tips for Calibrating Volumetric Glassware
Precise measurements are the cornerstone of successful laboratory work, isn’t? And to perform that volumetric glassware & volumetric equipment is the key. Calibrated glassware is available commercially, and in these cases, it is common to find such glassware coming pre-calibrated. This guide summarizes key considerations for calibrating volumetric apparatus including volumetric flasks.
“A glassware should be durable , resistant and ready for your experimentation”
So, prior to calibration, it is important to know how you can use and what volumetric flasks can do. A volumetric flask is a specific kind of a pear-shaped flask with a long neck, designed to contain a known volume of a liquid at a specific temperature. It is mainly used to make solutions of known concentration. So, a good way to learn how volumetric flask diagrams must be sketched is to learn about their construction and use. Volumetric flask uses are common to such fields from chemistry to biology and other scientific undertakings.
Volumetric Glassware Calibration Process:
- Cleaning: Thoroughly clean the volumetric flask with appropriate detergent, followed by rinsing with distilled water. Ensure complete dryness before proceeding.
- Weigh again: Weigh the flask full of water. Close this Window and accurately record this weight.
- Measuring: Weigh the empty flask and the filled flask, and subtract the two. This yields the weight of the water. Calculate the actual volume of the flask, using the known density of water at the required temperature.
- Correction factor: The ratio of the actual volume and the flask nominal volume Any difference establishes a correction factor to apply to subsequent measurements.
- Maintaining Accuracy: Calibration is needed to ensure its accuracy on a regular basis. Handling, cleaning and storage must be done properly. Steer clear of thermal shock that might take place the glassware volume. If using a volumetric flask, the bottom of the liquid meniscus should be exactly at the calibration line.
