Quality Control

Our Potassium Tartrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for all critical parameters are available upon request. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) or food-grade specifications (FCC) based on customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
