Magnesium Ribbon 25gm
Product Code : SCL-CLE-11895
JLab India Magnesium Ribbon is a high-purity metallic reagent (>99.5\text{%} Mg) engineered for empirical demonstrations of oxidation, combustion, and stoichiometry. Supplied in a 25g continuous coil, this ribbon provides a high surface-area-to-volume ratio, making it ideal for the rapid initiation of exothermic reactions. It is a staple consumable for Chemistry and Physics laboratories to illustrate the transformation of chemical energy into intense thermal and radiant energy.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Oxidation Interface: Facilitates the understanding of Synthesis Reactions. By burning the ribbon, learners identify the formation of Magnesium Oxide (2Mg+O2→2MgO) as a white powder.
- Stoichiometric Quantification: Enables mass-change experiments; learners apply gravimetric analysis to calculate the mass increase of the ribbon after oxidation in a crucible.
- Radiant Energy Analysis: Supports the analysis of "Exothermic Processes"; students evaluate the intensity of UV and visible light emitted during the combustion of alkaline earth metals.
- Reaction Rate Evaluation: Allows students to evaluate how surface area affects reaction speed by comparing the burning rate of the ribbon to magnesium turnings or powder.
Safety & Storage Protocol
CRITICAL SAFETY NOTE: Magnesium fires cannot be extinguished with water. Combustion produces intense UV radiation; direct observation without UV-rated eye protection should be avoided.
- Storage: Store in a cool, dry environment. Magnesium is sensitive to moisture and will gradually form a gray oxide/carbonate layer if exposed to humid air.
- Handling: Use crucible tongs or forceps when holding the ribbon in a flame.
- Disposal: Ensure all residues (MgO) are cool before disposal; treat unreacted metal as a flammable solid.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, airtight moisture-proof packaging. Each 25g coil is sealed in a heavy-duty poly-bag with a desiccant pack to prevent oxidation during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Analysis (CoA), and a comprehensive Safety Data Sheet (SDS) compliant with GHS standards.
- Regulatory: Classified as UN 1869, Magnesium, Hazard Class 4.1 (Flammable Solid) for international transport compliance.
Direct OEM Sourcing Advantages
Procuring JLab India Magnesium Ribbon directly ensures vertical manufacturing control:
- High Ductility: Our ribbon is manufactured to be flexible and easy to cut with standard laboratory scissors, preventing the brittleness found in low-grade alloys.
- Low Oxide Pre-load: Direct oversight of the drawing process ensures the ribbon arrives with minimal surface oxidation, allowing for immediate ignition without the need for intensive sanding.
- Direct Factory Inventory: Guaranteed availability of bulk "Lab Packs" (e.g., 10 or 20 rolls) to support high-enrollment chemistry departments.
- Quality Assurance: Every batch is tested for ignition reliability and purity to ensure consistent results in quantitative "Empirical Formula" experiments.
