Magnetic susceptibility balances

 
 

For Sale in North America and South America Only

The Magnetic Susceptibility Balance (MSB) determines the magnetic properties of solids and liquids at a glance. Johnson Matthey's state-of-the-art balance is based on the Evans design, and can be used to measure a wide range of paramagnetic and diamagnetic materials.

With applications in industrial chemistry, research and education, Johnson Matthey's MSB technology offers a number of significant advantages over traditional methods for measuring magnetic susceptibility.

The standard sample size is 250 mg, but using an ultra thin bore sample tube, an accurate measurement can be obtained with a sample as small as 50 mg.

Positive or negative readings from the display will indicate whether the material is paramagnetic or diamagnetic. A wide range of diamagnetic and paramagnetic materials can be measured.


  • More sensitive & reliable than the Gouy balance method
  • Compact
  • Portable - under 8 lbs.
  • Low cost
  • Sample size as small as 50 mg

The Mark I, which is an excellent teaching tool, has been used successfully in inorganic chemistry labs and other applications for over 11 years.

The features and operation of the Mark I , along with some experiments, are described in Microscale Inorganic Chemistry A Comprehensive Experience, Szafran, Z.; Pike, R.; Singh, M., John Wiley & Sons: New York, 1991.

Using the Mark I for determining magnetic susceptibility is simple: the length, weight, & balance readings are entered into an easy-to-derive equation.

The Mark II is 100 times more sensitive and can handle a wider range of paramagnetic and diamagnetic materials than the Mark I. Because the balance automatically calculates the volume and mass susceptibility, it is ideal for use in quality control or any applications where repetitive measurements are taken.

By utilizing the RS232 interface and software included with the balance, all measurements can be stored in your computer. Statistical analysis can then be performed on the sorted data.


Over 1000 MSB's are currently in operation in industrial and academic laboratories throughout the world. Its design was a result of collaboration between Johnson Matthey, Herts, England and Professor D.F. Evans of Imperial College, London, England.
