8600 Series VSM

More science, less time

Advanced measurement performance

The 8600 Series vibrating sample magnetometer raises the bar for magnetometer performance and convenience. These VSMs combine high sensitivity (15 nemu), rapid measurement speed (10 ms/pt), and simple operation for more accurate measurements, faster.

Convenient operation

The entire 8600 Series system has been reimagined with a focus on clean, ergonomic design that simplifies the researcher’s interaction with the system. A motorized head brings the sample to a comfortable height for easy, one-handed exchange of the QuickLIGN™ sample rods. Temperature options include a cryostat, high-temperature oven, and single stage variable temperature insert. The combined temperature range of the options is 4.2 K to 1273 K. All three GlideLOCK™ options quickly slide into place and are auto-detected, with the software automatically displaying controls for the specific option. The magnet poles are also easily adjusted with the ExactGAP™ indexed positioning system that allows the pole gap to be set at one of six repeatable positions, eliminating the need to recalibrate after each change.

 

Designed for FORC

This VSM was created with first order reversal curve (FORC) measurement as a primary objective. FORC analysis is greatly enhanced by the high sensitivity of the 8600 Series vibrating sample magnetometer. FORC also benefits from increased data point density, and the new VSM flies through complex FORC data collection sequences in a fraction of the time required on previous systems.

Flexible and adaptable

The system’s software simplifies control of the VSM. Standard predefined measurement routines are combined with configurable field and measurement loops to provide a flexible data acquisition environment. In addition, the software features an integrated scripting tool, which enables the user to extend the existing routines with an open-ended software scripting language that can be used to perform customized measurement protocols and interface with third-party lab equipment.
