The physicochemical index is general specification but we can customize product according to the requirements of customer.
Yeast peptone is suitable for microbial culture and provides comprehensive nutrition for bacterial growth.
Fully dissolved and sterilized before use.
Compound Paper Bag with 25kg/bag or Cardboard Bucket. Reagent-grade products are packaged with 250g plastic bottle (or be packed according to the measurement requirements of customer and OEM Package as well).
Yeast peptone is a nutritional supplement derived from yeast, widely used as a culture medium component in microbiology. It provides essential nitrogen sources, amino acids, and peptides to support bacterial and fungal growth.
Yeast peptone is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. Each grade meets the same core physicochemical standards, with differences in solubility and clarity specifications suited to different application environments.
Before use, yeast peptone should be fully dissolved in the appropriate volume of water and then sterilized — typically by autoclaving — to ensure a contamination-free culture medium.
Standard packaging is a Compound Paper Bag at 25kg/bag or a Cardboard Bucket for bulk supply. Reagent-grade products are available in 250g plastic bottles. Custom packaging sizes and OEM packaging are also available upon request.
Yes. While the physicochemical index listed represents the general standard specification, customized formulations and specifications can be arranged based on specific customer requirements.
Yeast peptone has a maximum moisture content of 6.0% and a pH range of 4.5–7.5 (measured as a 2% solution), ensuring product stability and consistency across all three grades.
