Frequently Asked Questions
What is beef extract and what makes it a high-quality nitrogen source for culture media?
Beef extract is a concentrated, water-soluble preparation derived from beef tissue. It is rich in peptides, amino acids, vitamins, and natural growth factors, making it an excellent nitrogen source that compensates for the nutritional deficiencies of peptone and other common media ingredients.
What are the key physicochemical specifications of this beef extract?
The product meets reagent-grade standards with total nitrogen ≥14.0% (on DM), amino nitrogen ≥2.5% (on DM), ash ≤13% (on DM), moisture ≤6.0%, pH 4.5–7.0 (2% solution), and pellucid solubility in 2% solution.
In which industries and applications is this beef extract commonly used?
It is widely used in biological research laboratories and large-scale microbial fermentation industries. It serves as a high-grade raw material for optimizing microbial cultivation efficiency, supporting strain activity, and enhancing the performance of culture media.
How should beef extract be prepared before use?
The beef extract should be fully dissolved in the appropriate volume of water and sterilized before use to ensure product safety and efficacy in microbial culture applications.
What packaging options are available for this beef extract?
The product is available in compound paper bags (25kg/bag) or cardboard buckets for bulk use. Reagent-grade products are also supplied in 250g plastic bottles. Custom packaging sizes and OEM packaging are available upon request to meet specific customer requirements.
Can the physicochemical specifications be customized for specific needs?
Yes. While the listed physicochemical index represents the general specification, we offer product customization to meet specific customer requirements. Please contact us with your detailed specifications for a tailored solution.
