Sherwood Scientific's Magnetic Susceptibility Balances Sherwood Scientific's Magnetic Susceptibility Balances are recognised in hundreds of teaching and research laboratories throughout the world. Based on a design by the Late Professor Evans of Imperial College London they offer a number of significant advantages over traditional methods. The Mk1 balance adheres closely to Evan's original design. The new Magnetic Susceptibility Balance - AUTO is a microprocessor controlled, state of the are balance for detecting the magnetic properties of gases, liquids and solids. The improved sensitivity, versatility and overall performance make it ideally suited for new analytical applications in the research laboratory and industrial quality control.
