What is beef extract used for in microbiology?
Beef extract is widely used as a nitrogen source in culture media for biological laboratories and large-scale microbial fermentation. It provides peptides, amino acids, and natural growth factors that support microbial growth and metabolism.
What are the key physicochemical specifications of your beef extract?
Our beef extract (reagent grade) features a total nitrogen content ≥14.0% (on DM), amino nitrogen ≥2.5% (on DM), ash ≤13% (on DM), moisture ≤6.0%, pH of 4.5–7.0 (2% solution), and a pellucid solubility in 2% solution.
Can the product specifications be customized?
Yes. While the physicochemical index listed represents our general specification, we can customize the product formulation and packaging according to the specific requirements of each customer, including OEM packaging options.
How should beef extract be prepared before use?
Beef extract should be fully dissolved in water and then sterilized before use in culture media preparation to ensure product safety and performance consistency.
What packaging options are available?
We offer compound paper bags at 25kg/bag and cardboard buckets for bulk use. Reagent-grade products are available in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available upon request.
