The Classic SteriSorb Ultra is a Sterile version of the Classic Ultra. It is a high capacity 7x16 inch (17x40cm) secondary absorbent pad designed specifically to meet the needs of wound clinicians. The SteriSorb Ultra can hold up to 1 liter of fluid with the fluid being wicked to the center of the product leaving the pad dry to the touch. It can absorb from both sides and can be doubled over for more absorbency. As this is a secondary absorbent product, something else would need to be in direct contact with the wound bed such as gauze or Adaptic, etc. For the non-sterile version, please see Classic Ultra - #41080.
