产品名称：MicroFirst® LP Low Endotoxin低内**洁净室湿巾

MicroFirst® LP LE is a non-sterile nonwoven low endotoxin wipe engineered for advanced performance and minimizing the presence of harmful endotoxins in the pharmaceutical, medical device, and other key regulated industries. Comprised of a specially formulated blend of polyester and DuPont Lyocell, this wipe excels at wiping delicate and scratch prone surfaces while providing outstanding absorbency. The advanced construction and particle entrapment capabilities serve as a powerful vehicle for removing endotoxins from surfaces, end-products, or processes without adding additional risk from sterile wipes not tested for endotoxin levels. 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.

MicroFirst®LP LE是一种非无菌无纺布低内**擦拭布，旨在提高性能，并大程度降低制药，医疗设备和其他关键监管行业中有害内**的存在。 由特殊配方的聚酯和杜邦莱赛尔纤维混合物组成，这种擦拭布擅长擦拭易碎和易刮擦的表面，同时具有出色的吸收性。 构造和颗粒捕获功能可作为一种强大的载体，用于从表面，产品或过程中去除内**，而不会增加未经湿巾测试的内**水平，而这些湿巾未经内**水平测试。 此外，我们所有的低内**擦拭巾均经过批量测试，以确保它们达到或*过USP和FDA标准（基于关键监管行业内**的大允许阈值）设定的要求。

FREQUENTLY ASKED QUESTIONS

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”
