Absorption / Retention
Absorption and Retention
Testing vs. brands
The absorbency was determined using the standard method
BS EN 13726-1:2002, Test methods for primary wound dressings
– Part 1: Aspects of absorbency. In summary a 5 x 5 cm foam
sample was weighed and placed into an excess saline solution
(Test Solution A*) to simulate a wound environment, for 30 minutes
at 37°C. The sample was then suspended vertically by the corner
of the dressing for 30 seconds and reweighed.
The fluid retention was measured using the saturated 5 x 5 cm foam sample. The sample was subjected to a 6 kg weight covering the total surface area of the dressing for 30 seconds. The weight was removed and the sample reweighed. Abderma foam routinely retains in excess of 90% of the absorbed liquid. This exceptional fluid handling property differentiates the Abderma foam from other foams currently available.
