Medical Grade Compounds for Molecular Diagnostic Instruments

With the proliferation of infectious diseases such as the latest strain of the coronavirus i.e Covid-19 worldwide, there is a critical need to develop tests, which can detect patients who have contracted the disease. Master Bond has been developing specialty medical grade adhesives, sealants, coatings, impregnation materials, and encapsulation compounds for medical device companies, which are the forefront of designing and manufacturing instruments that can detect such diseases. Molecular diagnostic technology and instruments are widely employed and recognized as not only an efficient and fast method of detecting diseases, but also as an accurate and reliable tool.

Master Bond has been helping medical device customers over the years, and our products have been widely employed in biosensors, microfluidic applications, and in the assembly of diagnostic instruments. One example is our structural adhesive EP31, which was successfully used for bonding acrylic and aluminum components, in a molecular diagnostic instrument, for a non-instrumented nucleic acid amplification system.1

Many Master Bond products meet the USP Class VI and/or ISO10993-5 test requirements. Some examples of systems which meet both USP Class VI for biocompatibility and ISO10993-5 for cytotoxicity are:
