Bluefors Oy (formerly BlueFors Cryogenics) specializes in cryogen-free, ultra-low temperature dilution refrigerator systems aiming to supply the highest possible quality products. We deliver systems for cutting-edge research fields such as quantum computing and nano-technology. Bluefors technology was developed at the world famous Low Temperature Laboratory (LTL) at Helsinki University of Technology (now Aalto University). In 2007 the first cryogen-free dilution refrigerator was taken into use by the NANO-group of the LTL, shortly after Bluefors Oy was established as a company. With over 600 systems installed worldwide, we are the leading supplier of cryogen-free dilution refrigerator systems.
