 MPMS SQUID VSM
|
- Data Acquisition - New FastLab™ data acquisition combines Quantum Design's dc SQUID sensor and novel Vibrating Sample Magnetometer technology.
- Temperature Control - RapidTemp™ is an innovative temperature control design that allows you to cool samples from room temperature to a stable 2 K in less than 30 minutes.
- Magnet Control - QuickSwitch™ offers you the ability to quickly and continuously ramp field, stabilize, and acquire data.

PPMS |
- Sealed sample chamber with 2.6 cm diameter sample access
- Novel sample mounts couple easily to the 12 electrical leads built into the cryostat insert
- The Model 6000 is a self contained microprocessor-controlled device, eliminating the need to use or purchase external bridges, current or voltage sources or lock-in amplifiers.
- Continuous Low-Temperature Control - maintains temperature below 4.2 K for indefinite periods of time and offers smooth temperature transitions when warming and cooling through the 4.2 K.
- Temperature Sweep Mode
- User Experiments - External instruments may be controlled automatically using Visual C++, Delphi or Visual Basic in our Windows-based MultiVu control software. Click here for more details. In addition, our Grapher utility displays data as it is being collected.
