Hyaluronic acid reagent

water analysisfor the cosmetics industryfor the pharmaceutical industry

Product overview
The Hyaluronic Acid kits enable colorimetric quantitative determination of sodium hyaluronate using a visible spectrophotometer. They are intended for pharmaceutical and cosmetic formulations, medical devices and fortified waters or dietary beverages containing added hyaluronic acid. Analysis of cross-linked (reticulated) hyaluronic acid is possible using the optional Cross-Linked HA supplement without changes to the test protocol. Liquid, solid and gel samples can be analysed; water dilution is required only when necessary.


Key points

Quantitative determination in liquids, solids and gels with minimal pretreatment (water dilution only if necessary).

Measurement with a visible spectrophotometer at 680 nm.

Shelf life: 12 months from production; reagents stable after opening.

No calibration curve required; results in ≈ 20 minutes.

Analytical range (without dilution): 0.001% – 0.01%.

Available formats: 40 tests and 80 tests.

Accuracy and repeatability suitable for quality control.
