Traditionally, water or saline solution has been used to extract endotoxin in tests involving medical devices and equipment; however, the efficacy of this extraction method is debated. In order to provide our customers with a more reliable method for medical device testing, FUJIFILM Wako has developed an endotoxin-free solution containing human serum albumin (HSA) that is capable of extracting endotoxins that cannot be extracted in water or saline solution.
