OptiStat DN - Liquid Nitrogen Cryostat

The Optistat DN liquid nitrogen cryostat and the ITC temperature controller from Oxford Instruments enables families of temperature dependent steady state and lifetime data to be acquired under computer control through the F900 Windows™ software. Temperatures from 77K to 300K (with a stability of ±0.1K) can be routinely measured and the temperature range can be extended to 500K upon request.

The cryostat itself is a static exchange cryostat and as such benefits from both uniform sample cooling and rapid sample exchange. 2 sets of  inner and outer windows are supplied for the standard L-geometry configuration but optical access can be provided via four sets of radial and one set of axial windows.

A variety of sample holders are available for cuvettes and solid samples. The cryostat comes complete with adapter, collar and pivot to allow it to fit the FLS920 series of sample chambers.
