Cell Culture and Viral Testing

Perfectus Biomed specialise in cell culture and viral testing. This includes biocompatibility testing, virucidal efficacy testing and viral barrier testing, to name a few.

Biocompatibility testing is essential to support the biological evaluation of medical devices. Perfectus Biomed use in vitro wound models and also cell models to aid biocompatibility assessments using ISO 10993 guidance. We measure parameters such as cytotoxicity, hemocompatibility, irritation, corrosion and proliferation viability.

Virucidal efficacy testing is important for assessing the activity of a variety of products against viruses. These products typically include both household and industrial disinfectants. Virucidal efficacy testing can be carried out by using either suspension tests or hard surface carrier tests. Perfectus Biomed also offer viral barrier testing for wound dressings and many other materials.

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