Glass Stirring Rod
Product Code : SCL-CLE-11908
The JLab India Glass Stirring Rod is a fundamental laboratory tool engineered for the manual agitation of liquids, the promotion of solute dissolution, and the controlled transfer of reagents (decanting). Unlike metallic stirrers, the high-purity glass construction is chemically inert, preventing contamination and catalytic interference in sensitive reactions. These rods are fire-polished at both ends to ensure user safety and to prevent scratching of delicate laboratory glassware.

Key Pedagogical & Laboratory Outcomes
- Agitation Interface: Facilitates the Dissolution Learners identify how mechanical stirring increases kinetic energy and surface area contact between solute and solvent, accelerating the formation of a solution.
- Decanting Application: Enables the technique of "Guided Transfer." Learners apply the rod against the lip of a beaker to direct the flow of liquid into a narrow-necked vessel, preventing splashes and ensuring quantitative transfer.
- Crystallization Analysis: Supports the analysis of "Nucleation"; students evaluate how scratching the side of a beaker with a glass rod can induce the precipitation of crystals from a supersaturated solution.
- Thermal Evaluation: Allows students to evaluate temperature distribution in a heated vessel; stirring ensures uniform heat transfer, preventing "hot spots" that could lead to glass fracture or uneven chemical reactions.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. Rods are bundled with protective interleaving and bubble-wrapped in batches of 10 or 25 to prevent mechanical snapping and surface scratching during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheet (MSDS).
- Durability: The Borosilicate 3.3 variant is specifically "annealed" to eliminate internal stress, making it rugged enough for daily use in high-traffic undergraduate laboratories.
Direct OEM Sourcing Advantages
Procuring JLab India Glass Stirring Rods directly ensures vertical manufacturing control:
- Superior Fire-Polishing: Direct oversight of the finishing process ensures that the ends are perfectly hemispherical and smooth, eliminating the "sharp edges" often found on low-cost alternatives.
- High Straightness Tolerance: We ensure that every rod is perfectly linear, which is essential for uniform stirring and safe storage in laboratory drawers.
- Direct Factory Inventory: Guaranteed availability of the full range of lengths and diameters to match specific beaker sizes and experimental requirements.
- Quality Assurance: Every batch is inspected for "seeds" or internal air bubbles that could compromise the rod's structural integrity when used with high-viscosity liquids.
