OptistatSXM2
ELIUM
low vibration helium bath cryostat,
sample in exchange gas
This high stability helium bath cryostat is ideal for low-vibration optical spectroscopy
and nano-scale microscopy. It offers a low base temperature (1.6 K), low levels of
vibration and fast sample change. The sample is cooled by a dynamic exchange gas
fed from an integral liquid helium reservoir. Its small footprint is ideal in laboratory
where space is limited. It doesn’t require any external dewar or transfer tube.
