    Packing & Storage
    Packing White, opaque plastic bottle labeled "Potassium Metabisulfite, 500g." Features hazard symbols, tight screw cap, and batch number for identification.
    Shipping Potassium Metabisulfite should be shipped in tightly sealed, clearly labeled containers to prevent moisture ingress and contamination. Store and transport it in a cool, dry, well-ventilated area away from acids and oxidizers. Comply with local, national, and international regulations for hazardous materials. Use suitable protective packaging and include safety documentation.
    Storage Potassium Metabisulfite should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible materials such as acids and oxidizers. The chemical should be kept in tightly sealed containers, clearly labeled, and protected from direct sunlight. Store away from foodstuffs and sources of ignition. Ensure that storage areas have proper spill containment and are equipped with safety equipment.
    Application of Potassium Metabisulfite

    Purity 99%: Potassium Metabisulfite with 99% purity is used in wine fermentation, where it prevents microbial growth and preserves flavor stability.

    Particle size <100 µm: Potassium Metabisulfite with particle size under 100 µm is used in food processing, where it promotes uniform dispersion and effective preservation.

    Molecular weight 222.33 g/mol: Potassium Metabisulfite of molecular weight 222.33 g/mol is used in beer stabilization, where it inhibits oxidative spoilage and maintains product clarity.

    Stability temperature 150°C: Potassium Metabisulfite with stability up to 150°C is used in juice pasteurization, where it ensures sustained antioxidant activity during heat treatment.

    Water solubility >250 g/L: Potassium Metabisulfite with water solubility above 250 g/L is used in photographic processing, where it enables rapid mixing and effective image development.

    Granular form: Potassium Metabisulfite in granular form is used in aquaculture water treatment, where it facilitates measured dosing and efficient dechlorination.

    Residue on ignition <0.05%: Potassium Metabisulfite with residue on ignition below 0.05% is used in pharmaceutical manufacturing, where it ensures high product purity and compliance with regulatory standards.

    Assay (as K2S2O5) ≥98%: Potassium Metabisulfite with an assay of at least 98% (as K2S2O5) is used in meat preservation, where it effectively inhibits bacterial spoilage and extends shelf life.

    Bulk density 1.5 g/cm³: Potassium Metabisulfite with a bulk density of 1.5 g/cm³ is used in chemical synthesis processes, where it allows for controlled metering and consistent reactivity.

    Oxidation resistance: Potassium Metabisulfite with strong oxidation resistance is used in bottled fruit preservation, where it minimizes color browning and maintains visual quality.
