The year 2025 marks a significant milestone for the Socorex Service Centre: 20 years of accredited calibration services. What began over 45 years ago as a side initiative to maintain the performance level of the instruments, has evolved into a key pillar of Socorex’s operations and a go-to provider of calibration services for laboratories across Switzerland, including the ISO 17025 accredited.
A track record of growth with no signs of slowing down
Alongside the manufacture of precision liquid handling instruments, Socorex was among the first companies in the 1980s to recognise the importance of repair and calibration services in maintaining reliability and performance of the instruments. Initially, the activity was carried out by a single person, steadily evolving into what is now known as the Socorex Service Centre.
Two milestones gave the Service Centre a decisive boost: the creation of dedicated laboratories and the achievement of ISO 17025 accreditation, granted by METAS (the Federal Institute of Metrology in Switzerland and a member of the International Laboratory Accreditation Cooperation, ILAC) in 2005. Since then, the Service Centre has grown continuously, expanding both its expertise and capacity. Today, with two ISO 17025 accredited laboratories and a skilled team of versatile technicians, the facility handles several tens of thousands of pipettes annually, servicing instruments of all major brands.

Over the past 20 years, the Socorex Service Centre has become a key accredited calibration provider for hospitals, research institutions, universities, and private industries . Thanks to its technical excellence, modern facilities, ability to handle all brands, consistent service and quick turnaround, it has established itself as a leading name in the Swiss market – with no signs of slowing down.
Results with the highest standard for confidence
What does ISO 17025 certification mean for the Socorex Service Center? It signifies that its calibration laboratories operate competently and generate valid and consistent results, thereby promoting confidence in their work both nationally and around the world. More importantly, this confidence has remained stable for over 20 years, with successful completion of rigorous audits by local authorities every five years.
Since receiving its first ISO/EIC 17025 accreditation in 2005, Socorex Service Centre experienced a dramatic increase in demand for accredited calibration services. This clearly reflects a general shift towards stricter quality assurance in various industry sectors. ISO/EIC 17025 is a part of that and a cornerstone of credible and compliant laboratory operations.
To meet diverse customer requirements, the facility proposes different service tiers, including those in full compliance with ISO 17025:
