Endotoxin Testing at LEAF

Endotoxins are toxic components found in the outer membrane of Gram-negative bacteria. They can contaminate water, medical devices, and clinical solutions and may cause fever, inflammation, or severe reactions in patients if present above allowable limits. The Endotoxin Test ensures the safety and microbiological quality of water used in healthcare applications. Endotoxin Tests at LEAF are conducted on Tuesdays, once per month.
