Optistat range product guide - Oxford Instruments

OptistatAC-V
2.8 k cryofree ® cryostat,
sample in vacuum
This cryostat is capable of achieving sample temperatures as low as 2.8 K without
the need for liquid helium. This brings significant benefits in terms of running cost
and ease of use.

•
Wide temperature range:
from 2.8 K to 325 K
Two models to choose from
depending on your cooling power
requirements
Low vibration using a Pulse Tube
Refrigerator. Typical displacement
amplitudes on the second stage
heat exchanger in the radial
and axial directions are typically
7 and 12 micrometers respectively
