Gamma Wipe® SuperSorb® Low Endotoxin
Gamma Wipe® SuperSorb® LE is sealed-edge sterile low endotoxin wipe engineered for maximum absorbency, critically low particle shed, and overall value. The knitted polyester construction provides a high level of chemical compatibility with common cleaning and disinfecting solutions, including isopropyl alcohol, phenols, bleaches, and quaternary ammonium compounds. The particle entrapment capabilities of this wipe serve as a powerful vehicle for removing endotoxins from surfaces, end-products, or processes without adding additional risk from sterile wipes not tested and verified for low endotoxin levels. Gamma Wipe® SuperSorb® LE is a validated sterile product that is gamma irradiated to assure consistent sterility. In addition, all of our low endotoxin wipes are lot-to-lot tested to ensure they meet or exceed the requirements set by USP & FDA standards based on the maximum allowable thresholds for endotoxins across key regulated industries.

What is a pyrogen (endotoxin)?

IEST-RP-CC023.2 defines a pyrogen as “A substance capable of producing fevers. The most common pyrogens are endotoxins, a class of lipopolysaccharides that comprise the outer wall of Gram-negative bacteria and are themselves byproducts of cell metabolism.”

Endo - Internal Toxin - Poison

Lipid A is the most toxic component of a gram-negative bacteria. It is embedded internally in the living bacteria.When bacteria is killed through cleaning, the outer cell wall detritus is released and the dead cell becomes toxic. It needs to be removed from the surface.

What are common sources of endotoxins?

Common sources of endotoxins are water, soil, vegetation, raw materials, poor equipment sanitization and maintenance practices.

What are examples of gram-negative endotoxins?

Burkholderia, Pseudomonas, Ralstonia, Escherichia, Serratia, Stenotrophomonas.

How do you test wipers for bacterial endotoxins?

Berkshire uses the LAL – Limulus Amebocyte Lysate test. FDA Guidance for Industry: Pyrogen and Endotoxins Testing “For more than 30 years, FDA has accepted the use of Limulus Amoebocyte Lysate LAL test for endotoxins in lieu of the rabbit pyrogens test.”

What is the frequency of endotoxin testing?

Berkshire tests each lot for endotoxins.

What are your guaranteed endotoxin limits?

<20 EU/device – <0.5 EU/mL

FDA Guidance for Industry: Pyrogen and Endotoxins Testing

“For medical devices...the limit is 0.5 EU/mL or 20 EU/ device for products that directly or indirectly contact the cardiovascular system and lymphatic system”
