Raw Materials

We offer a full spectrum of analytically-grade microbiological raw materials designed for consistent, reproducible microbial growth. Our portfolio features classic peptones (tryptone, casein peptone, proteose peptone, polypeptone, special peptone), nutrient extracts (beef extract powder, yeast extract powder, liver and heart infusion), selective salts (bile salt No. 3, desoxycholate salt), and bacteriological agar. Each product is produced under stringent quality controls, ensuring low endotoxin levels, minimal background interference, and precise nutrient profiles. Ideal for media preparation—from routine nutrient broths to differential and selective agar formulations—our ingredients support a wide range of microorganisms in academic research, pharmaceutical development, food safety testing, and industrial fermentation.

In the realm of microbiological research and industrial fermentation, the quality of raw materials is the keystone of reproducible results. Our Premium Microbiological Raw Materials portfolio brings together tried-and-true ingredients—such as Tryptone, Peptone from Casein, Soy Peptone, and Proteose Peptone—with precision-manufactured nutrient extracts like Beef Extract Powder and Yeast Extract Powder (Imported). Each component, from Bacteriological Agar to specialized salts like No. 3 Bile Salt and Desoxycholate Salt, is rigorously tested for purity and consistency.

Whether you’re formulating general nutrient media, selective plates for differential diagnosis, or high-performance fermentation broths, our range meets the demands of academia, pharma, and Food Safety laboratories. Our Casein Acid Hydrolysate and Gelatin Peptone provide unique peptide profiles, enhancing fastidious organism growth, while infusion products (Beef Heart and Liver) supply complex growth factors. With competitive pricing, reliable global supply, and full documentation (COA, MSDS), we ensure your research and production pipelines never skip a beat.

Choose our microbiological raw materials to elevate your culture media—experience minimal batch-to-batch variation, exceptional clarity, and unrivaled microbial support. Visit our website to browse the full catalog and request samples today.
