Sodium hyaluronate
Non-animal, bacterial-fermentation hyaluronate in six documented grades, each available across the full 15–1645 kDa molecular-weight window. The grade sets purity, endotoxin and documentation; you choose the molecular weight.

Assay is ≥ 95% on every grade. Every grade except the low-MW / oligo material is available across the full 15–1645 kDa window — you specify the molecular weight, we set the fermentation and downstream processing accordingly. Lot-specific results are stated on the certificate of analysis.
