About Biocompatibility Testing Services

Biocompatibility measures how compatible a device or component is with a biological system. The goal of this test is to determine how fit is a device for human use, and to diagnose any potentially harmful

physiological effects the device can have on humans

Two main processes are involved in biocompatibility testing.

1.      Toxicology: Unless otherwise engineered for safety purposes, this test type checks how toxic is a biomaterial when in use.

2.      Biocompatibility: The materials used need to be non-toxic to perform particular physiological functions. These functions include that of stent, knee replacement, dentistry equipment, surgical implants, and instruments. Thus, in short, biocompatibility will determine the ability of a material to co-exist and perform with a natural substance.

Mett-Bio metallurgical testing & services perform the following tests

1. ASTM F1089

This sub-category of biocompatibility testing evaluates the corrosion resistance of surgical

instruments. Most often, these instruments are reused in surgery and are fabricated from stainless steel

There are two unique test types in this method:

A. Boil Test

It detects free ions or any other anodic surface contaminants on stainless steel. This

method is applicable to austenitic, martensitic, precipitation hardening alloys, and ferritic materials.

B. Copper Sulphate Test

This test detects the presence of metallic ions and iron oxide on the

surface of the material. It is applicable to every above-mentioned steel type, except for martensitic

steels..
