Brass Test Tube Holder (Set of 12)
Product Code : SCL-CLE-11896
The StemAids 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. Manufactured to ISO 9001:2015 standards, 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
StemAids 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 StemAids 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.
