Quantum Design Magnetic Property Measurement System

The QDMPMS is used to analyse a wide variety of samples. On it's own it is capable of measuring magnetic properties of samples at temperatures between rough 4-300K. With a capacitance bridge attached to the probe we also use it to measure dielectric properties.

Three-zone tube and box furnaces

High-temperature (1700°C) furnaces see extensive use in our lab. Commonly used to grow single crystal samples, these have seen extensive use recently to perform chemical vapour transport growths. Additional uses include gas processing, when a glass tube is laid in the furnace and gas is pumped through it.
