Oxford Instruments is pleased to announce the latest version of their OptistatTMDry, further strengthening their Cryofree® optical cryostat family The new TLEX model provides cryogenic temperatures for sample-in-exchange-gas applications, with top loading sample change.

This cryostat is ideal for samples that are not suited to a vacuum environment due to poor thermal conductivity, including powders, or liquid samples. In addition, those who are running short experiments and want to maximise the throughput of samples will find the new TLEX version even quicker for sample exchange and just as easy to use as the OptistatDry sample-in-vacuum version.

A range of different designs of top-loading sample rods and sample holders are available to meet customer needs. This TLEX version provides a temperature range from <4 K to 300 K and a sample cool down time of less than 45 minutes.

“The new TLEX model brings the advantages of the OptistatDry family to sample-in-exchange-gas experiments. Reducing the time between experiments has been a key driver in the development of this product, enabling optical spectroscopists to study more samples in a given time”, commented David Clapton, Product Lifecycle Manager at Oxford Instruments NanoScience.

Dr Derren Heyes and his colleagues from the Manchester Institute of Biotechnology, University of Manchester, UK have recently created an application note called ‘Low temperature photolysis studies of vitamin B12 using a top loading OptistatDry’, where they measure low temperature absorbance spectra on samples that can only be cooled in an exchange-gas environment.
