Introducing a new disinfection system

Tristel Solutions Limited, a multi-brand group serving three markets in the health sector, developed the stella system, a high level disinfection system to make the disinfection of medical instruments faster and more thorough in order to reduce waiting time for patients. For this purpose, they needed a suitable material.


Meeting all requirements for disinfection systems

For Tristel, there were many factors to consider when finding a suitable material. One of those was the time required to disinfect medical equipment, which Tristel wanted to reduce significantly. On top of that, the disinfection system needed to be bio-compatible according to ISO 10993-1 test requirements.

To meet the requirements Tristel had with regard to its stella system, they turned to Apec 1745 high-heat polycarbonate from Covestro. Apec 1745 is unique in its ability to withstand temperatures as high as 134°C, significantly reducing the time required to disinfect medical equipment.
