AATCC TEST METHOD 100, ISO 11737- 1, ASTM E2149
MVTR – UKAS ACCREDITED TO ISO 17025, GLP COMPLIANT
WOUND CARE – FDA 510(K) SUBMISSION
AATCC Test Method 100, EN ISO 11737-1, ASTM E2149. MVTR – UKAS Accredited to ISO 17025. GLP Compliant. We can support with global regulatory submissions such as FDA 510(k)
Microbial infection is the cause of the majority of chronic wounds. As such, wounds that are not clinically infected are almost certainly colonised. These types of chronic wounds can therefore be deemed to be at risk of infection.
We support the research and development projects of companies who create products for chronic wounds. We aim to help decrease patient pain as well as the number of amputations resulting from long term chronic wounds, with the hope to improve patient quality of life. We carry out safety and efficacy testing to ATCC, BS EN and ASTM standards. Examples include AATCC Test Method 100, BS EN ISO 11737-1 and ASTM E2149. GLP compliant testing is also available.
Perfectus Biomed can also help support your regulatory submission and assist you in demonstrating the USP of commercially available products.

Moisture vapour transmission rate of permeable film dressings
The moisture vapour transmission rate (MVTR) of a dressing is an important property to assess and it plays a key part in assessing the fluid handling capabilities of a wound dressing. The use of this test allows us to determine if a dressing retains moisture in a wound, or wicks the moisture into the dressing, and away from the wound. The dressing can be tested when in contact with water vapour (to mimic dressings not in direct contact with the wound) and can be tested when in contact with liquid (to mimic dressings that are in contact with wound exudate).
