Synopsis

Discover a new micro-balance that lets you weigh minute quantities with precision and flexibility.

This book presents a micro-balance of a novel type, suspended by two silica fibers and operated by aerostatic compensation. It compares favorably with older instruments and enables measurements in a vacuum and under varying temperatures, including magnetic environments. The discussion covers design choices, experimental results, and the practical implications for high-accuracy weighings.

  • Introduction of a silica-fiber suspension and a new balance case for magnetic arrest and versatile environments.
  • How the balance achieves high sensitivity and stability while allowing weights in the milligram to microgram range.
  • Examples of experiments, such as observing weight changes in heated gold and exploring vapor pressures and gas adsorption effects.
  • Discussion of how instrument design affects accuracy, including reading methods, scale deflection, and environmental controls.
Ideal for readers interested in the history, design, and practical use of precision weighing instruments.
