Double Burette Clamp
Product Code : SCL-CLE-11945
The StemAids Double Burette Clamp is a high-precision fastening tool designed to hold two burettes simultaneously in a perfectly vertical orientation. This "dual-arm" configuration is essential for complex analytical procedures, such as back-titrations or the comparative analysis of two different titrants. Unlike standard utility clamps, the Double Burette Clamp features a unique central boss that mounts directly to a retort stand rod, ensuring that both burettes are equidistant from the support axis. Manufactured from die-cast aluminum or reinforced polymers, it is engineered to provide a secure, non-slip grip without obscuring the volumetric graduations.

Key Pedagogical & Laboratory Outcomes
- Efficiency Interface: Facilitates student understanding of High-Throughput Analysis. Learners identify how mounting two burettes allows for the rapid transition between an acid titrant and a base back-titrant without re-tooling.
- Alignment Application: Enables Perfect Verticality; the dual-clamp design ensures both instruments are parallel, allowing learners to apply consistent meniscus reading techniques across both data sets.
- Safety Analysis: Supports the analysis of "Vessel Integrity"; the padded "fingers" of the clamp distribute pressure evenly, helping students evaluate how to secure fragile glassware without causing "crush fractures."
- Contrast Evaluation: When paired with a white-enameled burette stand base, students evaluate the endpoint color changes with greater clarity, as the clamp holds the burettes at the optimal height for observation.
Design Variants: Metal vs. Polymer
- Die-Cast Metal: Preferred for high-temperature environments or where maximum mechanical rigidity is required. Usually features a high-visibility powder coating.
- Polypropylene (Plastic): Ideal for trace analysis or highly corrosive acid-leaching environments. These are naturally rust-proof and slightly lighter, making them easy for younger students to manipulate.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. Clamps are nested in shock-absorbent partitions to protect the spring mechanisms and prevent the grip pads from deforming during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheets (MSDS).
- Durability: Every clamp is cycle-tested to ensure the internal springs maintain consistent tension, preventing burettes from "sliding" even when fully loaded with high-density reagents.
Direct OEM Sourcing Advantages
Procuring the StemAids Double Burette Clamp directly ensures vertical manufacturing control:
- Unobstructed Sightlines: Direct oversight of the geometry ensures the "arms" of the clamp never overlap the graduation marks, a common defect in non-laboratory grade hardware.
- Symmetrical Tension: We ensure that both sides of the clamp provide identical pressure, keeping the titration setup balanced and preventing the retort stand from tipping.
- Direct Factory Inventory: Guaranteed availability of both Spring-Action (quick release) and Screw-Action (maximum security) models.
- Quality Assurance: Every batch is "slip-tested" with 100ml burettes filled with concentrated saline to ensure zero downward creep over a 24-hour period.
