At the same time, we have built a reputation for delivering results, meeting deadlines and paying strict regard to confidentiality.
The success of our business has developed in large measure through the loyalty and satisfaction of our customers. Over the years they have steadily increased their reliance on our business, and we conitinued investing in new laboratory equipment to better meet customer needs.
Our customers span sectors such as pharmaceuticals, fine chemicals, diagnostics, biotechnology. We work with leading players within these industries all over Italy and we will to expand our services throughout Europe.




We take responsibility for Quality. Our standars are not only a tool to fulfill the strictest requirements but a well-rooted system to speed up performance and achieve better results.


C4T Labs are ISO 9001 (Certiquality). Moreover the Research Centre received MIUR (MIUR – Italian Ministry of Education, University & Research) Accreditation in 2011 and was recognized as Innovative SME in 2015.


Thanks to Regione Lazio financing POR FERS LAZIO 2007/2013 – Attività 1.4 -1.7, we first implemented  OHSAS 18001 Certification (Certiquality) and we invested in the deployment of an advanced IT platform.
