Top 10 Millikan Oil Drop Apparatus Factory in the world 2026

Introduction to Millikan Oil Drop Apparatus

The Millikan Oil Drop Apparatus is a crucial scientific instrument that was developed by Robert A. Millikan in 1909. This apparatus played a pivotal role in determining the elementary electric charge. By observing tiny oil droplets suspended in an electric field, Millikan was able to measure the charge on individual droplets. Through painstaking experimentation and analysis, he found that the charges on the droplets were always integer multiples of a fundamental unit of charge, which is now known as the elementary charge (e ≈ 1.602×10⁻¹⁹ C). This discovery was a cornerstone in the development of modern atomic and quantum physics, providing direct evidence for the quantization of electric charge.

Today, the Millikan Oil Drop Apparatus is widely used in educational institutions to teach students about the principles of electrostatics, the quantization of charge, and experimental techniques in physics. It also serves as a fundamental tool for research in related fields. Here are the top 10 factories that produce high - quality Millikan Oil Drop Apparatus in 2026:
