Explanation of "Analytical Balance"
Definition:
An "analytical balance" is a special type of scale used to measure the weight of small amounts of substances very precisely. It is often used in laboratories for scientific experiments, especially in chemistry.
Usage Instructions:
When using an analytical balance, you need to make sure that it is on a flat, stable surface and that it is calibrated correctly for accurate measurements.
Always handle the substances carefully and use tools like tweezers or spatulas to avoid adding extra weight from your fingers.
Example Sentence:
"The scientist used an analytical balance to measure the exact amount of powder needed for the experiment."
Advanced Usage:
In more advanced scientific settings, analytical balances may display measurements in milligrams (mg), allowing for extremely precise measurements necessary for quantitative chemical analysis.
Word Variants:
Different Meanings:
