NU-Gel Alginate Hydrogel NU-GEL Hydrogel gently and effectively debrides and desloughs wounds and can be used to manage chronic wounds throughout all stages of the healing process.

NU-GEL Hydrogel has been proven to be long-lasting, with a mean wear time of 2.78 days - 38% longer than IntraSite Gel - before secondary dressing change was necessary.
