OptistatDry TLEX

Oxford Instruments

OptistatDry TLEX New cryogen free optical cryostat 4 K

The OptistatDry - TLEX model is ideal for samples that have low thermal conductivity, including powder or are in liquid form. Samples for biological, life science or chemistry experiments often can not go into a vacuum environment. The OptistatDry with its sample-in-exchange-gas environment provides all the cooling you need for. samples that are not suited for a vacuum environment.

Top loading capability

The OptistatDry - TLEX model is also perfect, regardless of what type of samples you have, if you need to minimise the time between experiments and maximise sample throughput. Removing the sample rod whilst the cryostat is kept cold enables you to swap from one sample to the next in just a few minutes. You can leave the cryostat in situ on the optical bench during sample change, eliminating the need for time-consuming re-alignment of your optical set-up.

Versatile
Ideal for a wide range of spectroscopy applications including Raman, FTIR, Photoluminescence, etc.
Designed to interface with all types of optical benches; the feet match both Imperial (1 inch spacing) and metric (25 mm spacing)

Upgradeable
Designed with a modular philosophy that allows the cryostat to evolve with your experiment, allowing you to start with a basic system and as experimental needs change, upgrade to additional functionality at a later date, for example, add extra wiring, different sample holders and windows
A wide range of different sample holders, windows and wiring options enable you to upgrade your system as your experimental needs develop

Optical excellence
The cryostat comes with f1 and large clear optical access as standard
A wide range of different window materials are available to suit different wavelengths; wedged windows and anti-reflection coatings are also available

Simple to use
No liquid cryogens are required
Air or water-cooled compressors are available; single phase electrical power means the system is easy to install in all standard laboratory environments

UV/Visible spectroscopy

Experiments at low temperatures reveal the interaction between the electronic energy levels and vibrational modes in solids

Infrared spectroscopy

Low temperature IR spectroscopy is used to measure changes in interatomic vibrational modes as well as other phenomena, such as the energy gap in a superconductor below its transition temperature

Raman spectroscopy

Lower temperatures result in narrower lines associated with the observed Raman excitations

Photoluminescence

At low temperatures, spectral features are sharper and more intense, thereby increasing the amount of information available

Electrical properties

Optical and electrical measurements including I-V curves
