From Sweden to the world
Rossix was founded by Dr Steffen Rosén who developed the first commercial chromogenic assay for Factor VIII. Today, we serve customers all over the world from our office located on the west coast of Sweden, in the building where the world's first chromogenic substrates for coagulation factors were synthesized. This is our legacy and expertise and we gladly share it with you!
