Electronic balances have become indispensable in high school and college chemistry departments. They offer unparalleled accuracy, crucial for experiments requiring precise substance measurements. Their popularity stems from ease of use, suitable for all skill levels.
To use the electronic balance:
Set up the balance on a stable indoor surface to ensure accurate readings.
Turn on the balance and wait for the digital screen to display zeroes.
Place the empty container for measurement on the platform using tongs or gloves to avoid contamination.
Use the "Tare" or "Zero" button to deduct the container's weight from future calculations.
Carefully add the substance to the container, avoiding surfaces that may add mass to it.
Record the measured mass shown on the digital display.
Electronic balances provide efficient and precise mass measurements, enhancing the reliability of chemistry experiments.
Electronic Balance and Analytical Balance are both precision instruments used in laboratories to measure mass. However, they differ in their level of accuracy, sensitivity, and the weight range they can measure.
Electronic balances are general-purpose scales used for weighing items with a moderate level of precision.
They typically have a higher capacity, often up to several kilograms.
They are less sensitive to changes in the environment, such as temperature and air currents.
They are generally less expensive and easier to use, making them suitable for routine measurements and educational purposes.
Analytical balances are highly precise scales used for measuring very small amounts of material, often down to microgram levels.
They are extremely sensitive to changes in the environment and are usually enclosed in a glass case to prevent air currents from affecting the measurement.
They require careful handling and regular calibration to maintain their accuracy.
They are more expensive and are typically used in professional laboratories for tasks that require a high degree of precision, such as pharmaceutical research or forensic analysis.
In summary, the choice between an electronic balance and an analytical balance depends on the level of precision required, the weight of the items to be measured, and the available budget.
