Cell Culture and Viral Testing

Perfectus Biomed specialise in cell culture and viral assays.

Biocompatibility testing is essential to support the biological evaluation of medical devices. Perfectus Biomed use in vitro wound models and cell models to aid biocompatibility assessments, measuring parameters such as cytotoxicity, hemocompatibility, irritation, corrosion, proliferation  viability.

Virucidal efficacy testing can be carried out using suspension tests or hard surface carrier tests. These methods can be used to assess a range of products for example household and industrial disinfectants. Perfectus Biomed also offer viral barrier testing for wound dressings and other materials.

We will work with you to help you understand the benefits of the different cell and viral models and to choose a test method that is most suitable for your product.
