Brass Test Tube Holder (Set of 12)
Product Code : SCL-CLE-11896
The JLab India Brass Test Tube Holder is a robust, spring-action manual tool engineered for the secure gripping and manipulation of test tubes during heating or chemical reactions. Constructed from high-quality brass, it offers superior corrosion resistance and thermal stability compared to wooden or steel alternatives. This set of 12 is an essential procurement for University and Secondary School chemistry labs, ensuring every student has a reliable safety interface when working with open flames.

Key Pedagogical & Safety Outcomes
- Thermal Safety Interface: Facilitates the safe heating of liquids. The length of the brass arm ensures the student's hand remains at a safe distance from the Bunsen burner flame and hot vapors.
- Procedural Application: Enables the development of proper laboratory technique; learners apply the holder to the upper third of the test tube, allowing for the angled heating required to prevent "bumping" or sudden boiling.
- Chemical Resistance Analysis: Supports the analysis of "Material Durability"; students evaluate how the brass construction resists degradation even when exposed to acidic fumes or accidental chemical splashes.
- Ergonomic Evaluation: Allows students to evaluate tactile control; the spring-loaded jaws provide a consistent "clamping force," reducing the risk of tube slippage during agitation or mixing.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. Each holder is individually protected within the set of 12 to prevent mechanical entanglement or scratching during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a "Best Practices" guide for laboratory safety.
- Durability: Brass is naturally spark-resistant and does not become brittle with age, ensuring these holders remain a safe classroom staple for many academic cycles.
Direct OEM Sourcing Advantages
Procuring the JLab India Brass Test Tube Holder Set directly ensures vertical manufacturing control:
- Tension-Calibrated Springs: Direct oversight of the spring manufacturing ensures that the jaws are neither too loose (risking tube fall) nor too tight (risking thin-walled glass breakage).
- Smooth-Finish Jaws: We ensure the clamping surfaces are free from burrs or sharp edges, protecting the exterior of your glassware from scratches.
- Direct Factory Inventory: Guaranteed availability of bulk sets to equip entire laboratory cohorts simultaneously with standardized equipment.
- Safety Engineering: The finger loops are designed to accommodate gloved hands, ensuring a secure grip during complex experiments.
