Sorbsan Silver Flat

Sorbsan Silver Flat is a sterile, non-woven, calcium alginate wound dressing, impregnated with silver, high in Mannuronic acid and low in Guluronic acid.


The fibres of Sorbsan Silver Flat swell and form Sodium-Calcium alginate gel in contact with wound exudate. The gel:

  • Provides a moist wound healing environment1
  • Conforms to the contours of the wound2,3
  • Atraumatic dressing removal3
  • Promotes haemostasis4,5
  • Minimises disruption to newly formed tissue6
Sorbsan Silver are broad spectrum antimicrobial dressings, effective against MRSA, VRE and MRSE7,8,9. The average silver content is 1.5%.
