CRYOSTATION – CROSSOVER PREMIUM (XP) SERIES
The CRYOSTATION® crossover premium (xp) platform integrates pumped liquid helium cooling technology with the benefits of an automated, closed-cycle (helium-free) cryostat. Leveraging many of the proven technologies found in the original Cryostation systems, the xp-series retains the level of reliability, flexibility, and usability required to become a workhorse in any lab. The platform offers a turn-key solution for the most demanding users, making it easier than ever to reach and maintain temperatures below 2K.
