Proteox™ dilution refrigerators from Oxford Instruments enable a step change in Cryofree® system modularity – designed for enhanced adaptability, reliability and increased experimental capacity. Opportunities to view systems before purchase can be limited so using this augmented reality app on your own device you can see several of our systems up close and in real size! Explore key features and details that will help you assess our Proteox family for your own applications. You’ll also be able to see the Proteox™ Secondary Insert – a customisable, self-supporting module which enables installation and exchange of full experimental set-ups – perfect for pre characterising your experiments before cooling down your dilution fridge or for the multi-system and multi-user lab. Our Proteox platform is optimised to provide long-term reliability, stability and ease of use – why not see it for yourself! Within this augmented reality app, you can view some of our cryogenic systems in life size, giving you the opportunity to place them in your lab space and see how they fit, get up close to different components within the system and envisage how you will fit your experiments on the different temperature stages. See our most popular dilution refrigerator the ProteoxMX with the Secondary Insert fully loaded and being inserted into the fridge. This Secondary Insert can be fully customised with wiring and components required to run many experiments that need more than just small line-of-sight ports. Here you will see a Secondary Insert with 16 amplifiers, 16 isolators, 16 output lines and 56 input lines, perfect for superconducting quantum computing applications. Our latest dilution refrigerator, the ProteoxS, is perfect for a variety of condensed matter physics experiments including device characterisation and optical experiments. It is the most compact system on the market that offers no compromise in its performance, having a base temperature of less than 10 mK at the push of a button. It is user friendly, easy to operate and reliable for both experiments and in the education of using cryogenic systems for the future cryogenic technicians and engineers.
