Stelar SRL is an independent company which was established in 1984 in Mede, Italy, with the objective of offering new accessories, equipment and services for NMR research. For many years Stelar was one of the few companies manufacturing low resolution NMR spectrometers, NMR software and upgrading kits for existing commercial NMR spectrometers. These activities allowed Stelar to acquire and consolidate a strong know-how in NMR instrumentation.


In 1994 Stelar embarked on a research and development project aimed at the development of advanced instrumentation for a novel low-field NMR technique, called Fast Field Cycling (FFC) NMR relaxometry. This challenging development was successful and allowed Stelar to introduce the first commercial FFC NMR instrument, called Spinmaster FFC, to the market in the 1997.


The first generation of Stelar FFC NMR relaxometers, named SPINMASTER, launched from the successful R&D projects, was installed at the University of Lund, Sweden.


The first FFC-NMR conference was held in Berlin and marked the start of the growing FFC-NMR community. The 11th FFC Relax conference was held in 2019 in Pisa, Italy (


EU PROJECT “IDentIFY” (Improving Diagnosis by Fast Field-Cycling MRI) launched with Stelar as a key partner. The objective of project IDentIFY is to bring FFC-MRI to the stage where it can be used as a routine tool for clinical diagnosis.
The FFC NMR method has been adopted in many NMR laboratories around the world and successfully applied in fields such as materials science (polymers, rock cores, electrolytes, etc.), biomedical research (MRI contrast agents, proteins, pharmaceutical formulations, etc.) and food science (quality control, origin of product, shelf life). Stelar is keenly focused on the development of new applications for FFC NMR which can lead to the increased awareness and use of FFC NMR for industrial research, development and manufacturing. Stelar’s experience and unique innovative technology has gained the company a strong reputation as the absolute leader in FFC NMR relaxometry. Indeed, Stelar is dedicated to continuous development of FFC NMR instrumentation by employing methods which exploit the latest technologies in electronics design and by integrating FFC NMR with other related techniques.
