Product Description
Tryptone Tellurite Agar Base is a specialized microbiological medium designed for the selective isolation and identification of Corynebacterium diphtheriae, the causative agent of diphtheria. This medium is widely used in clinical and research laboratories for diagnostic purposes.
The agar base contains tryptone, which provides essential nutrients for bacterial growth, while potassium tellurite acts as a selective agent, inhibiting the growth of most other bacteria. This allows for the clear identification of C. diphtheriae colonies, which typically appear black or grayish due to tellurite reduction.
Whether you’re a student, researcher, or educator, this medium is an essential tool for microbiology studies. At eqipped, we ensure you get high-quality lab supplies delivered to your doorstep, so you can focus on your experiments without worrying about sourcing reliable materials.
