The Thermo Scientific™ Oxoid™ Agar Technical No. 2 is a technical-grade bacteriological agar that conforms to the specifications of the U.S. Pharmacopoeia (USP) and American Public Health Association (A.P.H.A.).
It provides high gel strength and forms a firm gel at 1.2% w/v, making it ideal for media preparation where clarity and optical quality are not critical.
Agar Technical No. 2 is suitable for a variety of routine laboratory applications, including the preparation of culture media for general bacteriological work, environmental testing, and other standard procedures requiring a reliable gelling agent.
Key Features
- Conforms to USP and A.P.H.A. standards for technical-grade agar.
- High gel strength ensuring firm and consistent gel formation at 1.2% concentration.
- Reliable performance for routine microbiological media formulations.
- Faintly opalescent clarity suitable for applications where transparency is not essential.
- Batch tested for chemical and microbiological quality, including freedom from toxic substances and thermophilic contamination.
