Quantum Design PPMS DynaCool

Cryogen-free Physical Property Measurement System

The PPMS DynaCool, uses a single two-stage Pulse Tube cooler to cool both the superconducting magnet and the temperature control system, providing a low vibration environment for sample measurements.

Utilising a new approach to cryocooler equipment design, the PPMS DynaCool employs a unique 4He-based gas flow control system that gives you the rapid temperature cycling and accurate temperature control that you have come to expect from a PPMS.

The PPMS DynaCool also comes standard with an integrated Cryopump used to pump out the sample space to a vacuum of < 10-4 Torr.  This makes the PPMS DynaCool compatible with all the available options, or any other user-designed experiments, right out of the box.
