CHEMICAL BALANCE

Purpose :

The balance is used to measure mass to a high degree of precision.

Scope :

To assess specific gravity of formulations and to measure reagents, bhasma, churna etc.

Procedure :

• Check whether the sensitivity of the balance is appropriate for the amount of material to be weighed.

• Zero the balance before use.

• Put material to be weighed in a suitable container or on weighing paper, never directly on the pan of the balance.

• Determine the mass of the weighing container or paper.

• Place the material to be weighed in the container or on the weighing paper in the middle of the pan to avoid corner-load error.

• To prevent contamination of stock material, do not return unused substance to the stock bottle.

• Clean the balance with a soft, clean brush after use.
