The Original Thin Dense Chrome
Since 1945



Since 1992 Electrolizing® has housed its sister company ME-92 Operations, Inc. in the same Providence, RI production facility. ME-92 Operations specializes in industry-leading biocompatible coatings for medical tools and devices, offering both the ME-92® coating and the biocompatible version of the AL-COAT® coating specifically suited to medical applications.


ME-92® coatings are precise, biocompatible, and pure metallic chromium coatings for medical, surgical, laboratory, and clean room environments. Highly trained coating professionals and strict process controls allow for a uniform coating that is unparalleled in performance.

The coatings are completely inert, non-magnetic, and USP 10993-10, 10993-6, and 10993-11 tested. It may also interest you to know that Electrolizing® has a sister company, ME-92®, that specializes in biocompatible chromium coatings that were developed for application in the medical device industry.

NAMSA Test Results:

United States Pharmacopeia; ISO 10993-10
USP Intracutaneous Study
No Localized Tissue Reaction
Irritation tests are utilized to assess the irritation potential of medical devices, bio-materials, or their extracts exposed to eye, skin, or mucous membranes. The test(s) are performed using a model appropriate for the route (skin, eye, mucosa) and duration of exposure or contact.
United States Pharmacopeia; ISO 10993-6
USP Muscle Implantation Study 7 Day
Non Irritating to Muscle Tissue
Implantation tests are performed to evaluate the local d pathological effects on living tissue, at both the gross level and microscopic level, after implantation of samples of medical Implantation tests are performed to evaluate the local pathological effects on living tissue, at both the gross level and microscopic level, after implantation of samples of medical devices or bio-materials. The implant location is based on the clinical site of use. Implant duration’s are based on the need to evaluate the tissue response over multiple intervals and along with the sample’s inertness and absorptive characteristics.
U.S. Pharmacopeial Convention; ISO 10993-11
Acute Systemic - No Systemic Toxicity
No Systemic Toxicity
Systemic Toxicity tests evaluate the generalized biological effects to organs and tissues following exposure to a medical devices, bio-material, or their extracts. The term systemic implies that the exposure occurs by one route and the toxic substance is carried to distant locations causing an adverse effect. Systemic toxicity is typically evaluated in studies of acute, sub-acute, sub-chronic, and chronic duration based on the device’s intended exposure.
