Quality Control

Our Porphyran is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and purity. While specific grades are available, our standard quality control includes parameters such as sulfate content, carbohydrate profile, and microbial limits. A comprehensive Certificate of Analysis (COA) detailing purity, identification, and safety specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
