Tryptic Soy Agar (TSA) is a widely used, general-purpose microbiology medium made from enzymatic digests of casein and soybean meal, providing essential nutrients like amino acids, peptides, and carbohydrates that support the growth of a broad spectrum of bacteria. Sodium chloride is added to maintain osmotic balance, and agar is used as a solidifying agent to provide a stable surface for colony growth. It offers a balanced nutrient environment, facilitating cultivation, isolation, and enumeration of both fastidious and non-fastidious microbes.

Due to its versatility, TSA is extensively used for routine culture storage, microbiological testing, and research applications. While TSA alone cannot isolate specific pathogens, it remains the foundational medium for many clinical and industrial microbiology laboratories because of its balanced nutrient profile and dependable performance.

We provide TSA in a wide selection of convenient, ready-to-use, pre-poured agar plates. These sterile plates are available in a variety of specialized formulations to meet diverse laboratory needs, including formulations supplemented with lecithin and Tween, sheep blood-enriched or animal-free plates, and antibiotic-containing plates, such as those containing chloramphenicol, for selective applications. Our plates provide consistency and ease of use, enabling selection of the optimal medium tailored to your experimental or analytical testing requirements.

We manufacture more than 25 different TSA formulations that are available in various plate formats, including bottled agar and settle plates, all with strict quality control to ensure high performance, consistent formulation, and sterility. Our commitment to quality ensures optimal bacterial growth, accurate results, and reproducibility across applications, from R&D to pharmaceutical QC, environmental monitoring, industrial biotechnology, and food, beverage, and cosmetics testing.

If you don’t see what you’re looking for, we can efficiently manufacture a tailored solution to meet your needs, including custom fill volumes, formulations, antibiotic combinations (up to 5), and plate formats to fit your TSA plate requirements.
