Unitary Cryostats

In unitary cryostats, there is a common vacuum system for the endcap/coldfinger and the dewar. This provides efficient cooling in a variety of configurations. The endcaps may be in a fixed horizontal or down-looking vertical design. The horizontal cryostats are also available with an extended coldfinger arm for insertion into a low-back-ground counting chamber. The cryoflex option is a swivel arm which allows the endcap to be aimed for maximum efficiency. Cryostats for X-ray detectors may be ordered in a fixed horizontal geometry or with a slide mechanism for adjusting the endcap-to-sample distance. A variable-z control is also offered for detectors mounted on an electron column. These dewars are available in several standard bucket sizes, as well as special portable models.
