Coronavirus / COVID-19

Dear Partners/Colleagues,

Throughout these difficult times, the Institute of Isotopes Co. Ltd. continues its production and the supply of the various pharmaceuticals, in vitro diagnostic kits and other key products in the use of medicine, science and technology to support patients and to assist customers.

For the sake of the safety of our employees, we have implemented security measures at our production sites as well as at the supply chain and the packaging process to limit the spread of the virus. Where it is allowed our employees are teleworking, but who must be present to complete their key functions have reorganized their work zones to implement social distancing in production, quality control, quality assurance, and administrative business units.
We have been able to secure the key materials and supplies to ensure the continuity of our activities.
We constantly monitor the global situation, especially the operation of airlines, and are committed to finding alternative routes to avoid the disruption of your service.
Should you need any special assistance or you have doubts, please do not hesitate to contact our dedicated Sales Team at:

In the meantime on behalf of Izotop’s team, I wish you good health and safety.
