Oxoid™ Tryptone Soya Agar (Soybean Casein Digest Agar) (Dehydrated) is a general-purpose, non-selective medium formulated for the cultivation of a wide variety of fastidious and non-fastidious microorganisms. It supports the growth of both aerobes and anaerobes and is widely used in clinical, pharmaceutical, and food microbiology laboratories.

Supplied in a 2.5 kg dehydrated powder format, this medium yields approximately 75 litres of prepared agar, making it ideal for high-throughput microbiological laboratories and quality control environments. It conforms to formulations detailed in international pharmacopoeias, including EP, USP, JP, and BP.

Key Features:

• Form: Dehydrated powder
• Weight: 2.5 kg
• Application: Cultivation of a wide range of microorganisms in clinical, pharmaceutical, and food microbiology
• Composition (per liter):
• Pancreatic digest of casein: 15.0 g
• Enzymatic digest of soybean meal: 5.0 g
• Sodium chloride: 5.0 g
• Agar: 15.0 g
• Final pH: 7.3 ± 0.2 at 25°C
• Preparation: Suspend 40 g in 1 litre of distilled water, bring to the boil with frequent agitation to dissolve completely. Sterilize by autoclaving at 121°C for 15 minutes. Cool to 50°C, mix well, and pour into sterile Petri dishes.
• Yield: Approximately 75 liters of prepared medium
• Standards: Complies with EP, USP, JP, and BP formulations; suitable for sterility testing and antibiotic susceptibility testing
