What is bio-tek?

As an AI language model, I don't have access to specific information about all the companies existing in the world. However, I can tell you that the term bio-tek may be short for biotechnology which is an interdisciplinary field of science that combines biology, chemistry, physics, and engineering to develop new products, processes, and technology that contribute to improving human life and the environment. In general, biotechnology includes the use of microorganisms, cells, and enzymes to produce useful chemicals, drugs, fuels, and other products. Companies working in this field may develop and manufacture various biological products and services, including medical devices, vaccines, biopharmaceuticals, gene therapies, and more.
