Mag-Instruments - Variable Field Translation Balance (VFTB) Portable Spinning Magnetometer
The Variable Field Translation Balance (VFTB) is a cutting-edge instrument offered by Mag-Instruments, designed for precise and simultaneous measurements of magnetization and susceptibility. This portable spinning magnetometer is recognized for being the most cost-effective solution with such advanced capabilities, making it a singular choice for researchers and professionals in the field. Its large sample capacity and user-friendly sample mount enable quick and efficient sample handling. The VFTB operates on principles that render it immune to the magnetic noise in its environment, negating the need for additional shielding. Integrated heating capabilities simplify its operation, requiring no adjustments. The system provides comprehensive measurement types, including thermomagnetic curves at temperatures as low as -180°C. The VFTB's precision is further demonstrated through examples of thermomagnetic and hysteresis measurements across various temperatures, showcasing its ability to handle diverse material analysis.Most popular related searches

VFTB is a sensitive and versatile instrument for measurement of magnetic properties of materials. Due to its high sensitivity, it is an ideal instrument for research in Rock Magnetism and Environmental Magnetism and can measure weakly magnetic materials, such as sandstone, limestone, soil etc. It can also be used for magnetic analysis in the field of material science e.g. analysis of synthetic materials, thermal behavior of permanent magnets etc.
It is the only instrument on the market that can simultaneously measure the reversible and irreversible components of magnetization and their temperature dependence. This makes it an instrument that is particularly suited for discrimination of different magnetic phases in the sample. We offer VFTB in two versions: SOLENOID – in which the main magnetizing unit is a solenoid capable of producing 300mT field. This version can perform measurements in the temperature ranging from the room temperature to 800°C. Due to the special design of the measurement unit with a much bigger sample chamber, it is more sensitive than the electromagnet version. This version is especially suitable for environmental studies. ELECTROMAGNET – in which the main magnetizing unit is a 1T electromagnet (see the image). This more powerful version can perform measurements in a full temperature range (-180 – 800°C). |
