PPMS® DynaCool™
The popular Physical Property Measurement System (PPMS) from Quantum Design is now available in a truly cryogen-free package. The PPMS DynaCool, Quantum Design’s latest development effort, 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. Utilizing 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!
