Hemolysis Testing

Yes, many single-use medical devices are coated — especially when performance, sterilization resistance, or biocompatibility is required. Common coatings include biocompatible chromium (like Armoloy ME-92), PTFE, and Parylene, depending on the device’s function.

Coatings are used to reduce friction, improve cleanability, or prevent corrosion on tools such as catheters, guidewires, or surgical blades. However, not all disposable devices are coated; cost, sterilization method, and regulatory approval influence this decision.

For example, ME-92 is often applied to reusable surgical tools, but may also be used on high-performance single-use components that require ISO 10993 biocompatibility.

Yes, as long as the weld is machined and blended. This is a positive application to consider since a welded area is very susceptible to corrosion during autoclave.

Biocompatible coatings enhance the durability, safety, and performance of surgical instruments by preventing corrosion and wear while ensuring they remain safe for use in the body.

A disposable medical instrument must perform as well as a reusable device and even disposable instruments require autoclave prior to use. Disposable instruments experience galling and dulling of edges during their short usage, but still must perform to a high level. The ME-92® biocompatible coating reduces these undesirable occurrences.
