Sorbsan Flat

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


The fibres of Sorbsan 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
  • Quick and easy to remove by irrigating with saline (0.9%) solution4
  • Promotes haemostasis5,6
  • Minimises the disruption of newly formed tissue7
