Micro-Balances – Description

Analytical Balances

Principle and Applications

A Micro-balance is an ultra-high precision laboratory weighing instrument designed to measure extremely small masses with very high accuracy. These balances are used in advanced

scientific laboratories, nanotechnology research, pharmaceutical analysis, forensic science, biotechnology, and calibration laboratories.

Micro-balances can measure masses in the microgram range.

Typical readability:

$1\mu g=0.000001\text{g}$

Some advanced micro-balances can even measure below one microgram.

Working Principle of Micro-Balance

Most modern micro-balances work on the Electromagnetic Force Compensation (EMFC) principle.

Working Process

1. A tiny sample is placed on the weighing pan.

2. The balance detects gravitational force.

3. An electromagnetic force is generated to counterbalance the sample weight.

4. Electrical current required for equilibrium is converted into mass.

Fundamental Equation

$F=mg$

Where:

• $F=\; Force$

• $m=\; Mass$

• $g=\; Acceleration\; due\; to\; gravity$
