Oxford Instruments launches TLEX - a new model of their OptistatDry for sample-in-exchange-gas applications

Oxford Instruments has annouced the latest version of their OptistatDry. The new TLEX model continues to strengthen their their Cryofree® cryostat family and provides cryogenic temperatures for sample-in-exchange-gas applications, with top-loading sample change.

The TLEX model has been designed for samples that are not suited to a vacuum environment, including powders, or liquid samples. In addition, those who need to maximise the throughput of samples for short experiments will find the new TLEX version even quicker for sample exchange and just as simple to use as the OptistatDry sample-in-vacuum version, providing 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.


A range of different designs of top-loading sample rods and sample holders are available.

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. The application note can be downloaded from http://www.oxinst.com/optistatdry.
