Precautions while using a density bottle are:
- A density bottle is a bottle whose volume is known its empty weight is measured and then weighted containing liquid whose density needs to be determined.
- Precaution that should be taken while measuring the density using the density bottle is that it should be carefully handled by holding the bottle by its neck to avoid expansion.
- The glass bottle with which the density is to be determined should be completely dry from the inside as well as outside.
- The glass density bottle should have contained any kind of bubbles in it. Since the bottle has a fixed and known volume presence of any kind of bubble in it may cause a change in its volume leading to an error in the density calculation of the desired sample.
