Microbiological media products are essential for isolating and identifying microorganisms within the lab. At Thomas Scientific, we have an extensive range of high-quality microbiological media products and accessories to assist with laboratory applications. Microbial culture media supports the survival and growth of various bacteria types, such as bacteria, fungi, and viruses. Microbial culture media can be prepared in various forms. The key microbiological products include liquid (broth), solid (agar plates), or semi-solid (deep). Microbiological media products can provide the correct nutrients, environment, and selected conditions to suppose the growth and continuous study of microorganisms and can ensure you achieve accurate and reliable results.



For further related products also available at Thomas Sci we provide samplers and tissue culture media.
