Bunsen Burner (Pack of 2)
Product Code : SCL-CLE-11893
The JLab India Bunsen Burner is a foundational laboratory heating instrument engineered for the controlled combustion of gaseous fuel (Natural Gas or LPG). Designed to produce a single, continuous open flame, it allows for precise adjustment of both gas flow and air intake to regulate flame temperature and chemistry. This pack of two is an essential procurement for University and Secondary School Chemistry, Biology, and Physics laboratories for sterilization, combustion, and heating applications.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Combustion Interface: Facilitates student understanding of the relationship between fuel and oxygen. By adjusting the collar, learners identify the difference between a "safety flame" and a "roaring blue flame."
- Flame Quantification: Enables the study of thermal zones; learners apply the burner to locate the hottest part of the flame (the tip of the inner blue cone).
- Chemical Analysis: Supports the analysis of "Flame Tests"; students evaluate the characteristic color changes when different metal ions are introduced into the oxidizing zone.
- Sterilization Evaluation: In microbiology, allows students to evaluate aseptic techniques, such as "flaming" inoculating loops to prevent cross-contamination.
Operating Zones of the Bunsen Flame
- Safety Flame (Yellow): Air hole closed. Incomplete combustion results in a luminous, relatively cool flame (300?C).
- Oxidizing Zone (Outer Blue): High oxygen mix. Used for heating and oxidation reactions.
- Reducing Zone (Inner Blue Cone): The hottest part of the flame is located just above this tip.
- Hottest Zone: Reached when the air hole is fully open, creating a "roaring" sound and a distinct double-cone structure.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade secure packaging. Burners are individually boxed and protected by shock-absorbent internal bracing to prevent barrel misalignment during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a safety manual detailing leak-testing and lighting procedures.
- Durability: All components are treated with high-temperature resistant plating to prevent corrosion and carbon buildup, ensuring a multi-year service life in intensive lab environments.
Direct OEM Sourcing Advantages
Procuring the JLab India Bunsen Burner directly ensures vertical manufacturing control:
- Stability Engineering: Direct oversight of the die-casting process ensures a heavy, balanced base that significantly reduces the risk of accidental tipping—a critical safety factor in student labs.
- Precision Air-Gap Machining: We ensure the air-control collar rotates smoothly without sticking, allowing for granular control over the flame's oxygenation.
- Fuel Specificity: Every order is verified for local gas standards (LPG vs. Natural Gas) to ensure the jet orifice is correctly sized for safe, efficient combustion.
- Quality Assurance: Every burner is pressure-tested at the factory to ensure there are no gas leaks at the intake or the valve junctions.
