Three Prong Clamp
Product Code : SCL-CLE-11939
The StemAids Three-Prong Clamp (Universal Utility Clamp) is the most versatile fastening tool in the laboratory, designed to secure a vast range of glassware from small test tubes to large burettes and flasks. Featuring a unique "two-on-one" finger configuration, it provides a stable, tripod-like grip that automatically centers the object. Manufactured from high-strength die-cast alloy with heat-resistant sleeves, it is the primary support interface for titration, distillation, and sensor mounting.

Key Pedagogical & Laboratory Outcomes
- Universal Interface: Facilitates student understanding of Mechanical Equilibrium. The tripod design ensures that even irregular or tapered glassware is held at three distinct points, preventing the "wobble" associated with two-prong clamps.
- Volumetric Application: Enables the perfectly vertical mounting of Burettes and Eudiometers; learners apply the clamp to ensure that volumetric readings are not skewed by a tilted vessel.
- Thermal Analysis: Supports the analysis of "Expansion and Contraction"; the padded sleeves act as a buffer, allowing students to evaluate heated reactions without the glass cracking against cold metal prongs.
- Sensor Evaluation: Ideal for holding delicate probes and thermometers; learners evaluate temperature gradients by precisely positioning sensors at specific depths within a solution without the risk of the probe touching the vessel walls.
Operational Mechanics: The Tripod Advantage
The three-prong configuration is mathematically superior for stability:
- Self-Centering: As the screw is tightened, the single finger pushes the object into the "V" created by the opposing two fingers, automatically aligning the glassware.
- 360° Access: The narrow profile of the prongs ensures that the majority of the glassware remains visible, which is critical when monitoring phase changes or precipitate levels.
- Variable Diameter: Unlike fixed-size clips, the three-prong clamp can transition from holding a 5mm glass rod to a 80ml flask neck instantly.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. Clamps are packed in nested cartons to protect the adjustment threads and ensure the sleeves remain uncompressed during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheets (MSDS) for the sleeve materials.
- Durability: The internal spring mechanism is fatigue-tested to ensure it maintains consistent tension over thousands of open-close cycles in high-traffic undergraduate labs.
Direct OEM Sourcing Advantages
Procuring StemAids Three-Prong Clamps directly ensures vertical manufacturing control:
- Premium Sleeve Bonding: Direct oversight ensures that the PVC or rubber sleeves are thermally bonded to the prongs, preventing them from sliding off when exposed to steam or solvents.
- Corrosion-Resistant Plating: We use a thick chrome or powder-coat finish that resists the "pitting" caused by chronic exposure to acid fumes in fume hoods.
- Direct Factory Inventory: Available in both Single Adjust (standard) and Dual Adjust (for centering very large objects) versions.
- Quality Assurance: Every batch is "torque-tested" to ensure the thumb-screws do not strip or seize under the typical pressures of a busy laboratory.
