SatPax® MicroSeal®-VP WFI Low Endotoxin
SatPax® MicroSeal®-VP WFI LE is a non-sterile pre-saturated polyester sealed-edge low endotoxin wipe that provides maximum protection when it comes to critically low particle generation, chemical compatibility, and abrasion resistance for the most critical cleaning applications for the medical device, pharmaceutical, and other regulated industries where the smallest measure can make the biggest difference. This wipe is pre-wetted with a 70% IPA and 30% WFI (water for injection) prepared using a validated aseptic sterile filtration process. Our patented surface treatment enables the SatPax® MicroSeal®-VP WFI LE to capture and retain particulate contamination including endotoxins well beyond the capabilities of a typical polyester sealed edge clean room wipe. In addition, a no-run interlock knit construction provides a smooth surface texture and excellent absorbency. 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.

* Alcohol content less than 70% is not currently recommended for surface disinfection by the CDC.

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”
