Burette Stand
Product Code : SCL-CLE-11940
The StemAids Burette Stand is the foundational structural support for volumetric analysis. Unlike a standard retort stand, this specialized assembly is optimized for titration, featuring a heavy-duty, chemical-resistant base and the iconic Fisher-type double clamp. This configuration allows for the simultaneous mounting of two burettes, facilitating back-titrations or the comparison of different reagents. Manufactured to institutional durability standards, it provides the absolute vertical stability required for accurate meniscus readings.

Key Pedagogical & Laboratory Outcomes
- Stability Interface: Facilitates the understanding of Vertical Alignment. Learners identify how a weighted base prevents "tipping" when burettes are filled, ensuring the 0ml mark remains stable during the experiment.
- Volumetric Application: Enables high-precision Titration Analysis; the Fisher clamp design ensures that burettes are held perfectly parallel, allowing learners to apply reagents to two different samples simultaneously.
- Ergonomic Analysis: Supports the analysis of "Operating Clearance"; students evaluate the benefit of the white-enameled base, which provides a high-contrast background to clearly see the color change of indicators like Phenolphthalein.
- Safety Evaluation: Provides a platform for evaluating glassware protection; the "finger-press" mechanism of the Fisher clamp allows for one-handed adjustment, reducing the risk of crushing the thin glass walls of the burette.
The Fisher Clamp Advantage
The Fisher-style clamp is preferred in analytical labs for three primary reasons:
- Unobstructed View: Unlike utility clamps, the Fisher clamp does not obscure the graduation marks on the burette, allowing for clear readings from 0 to 50ml.
- Spring-Loaded Ease: The spring mechanism provides a consistent clamping force—strong enough to hold a full burette, yet gentle enough to avoid glass stress.
- Dual Mounting: It allows a "Master" and "Duplicate" titration to be set up side-by-side, increasing laboratory throughput.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade flat-pack packaging. The heavy base and slender rod are packed separately within the same carton to prevent the base from bending the rod during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and assembly instructions.
- Durability: The base is treated with a specialized chemical-resistant coating that prevents "pitting" when exposed to common laboratory acids or bases (HCl, NaOH).
Direct OEM Sourcing Advantages
Procuring the StemAids Burette Stand directly ensures vertical manufacturing control:
- Base Weight Calibration: Direct oversight ensures the base is heavy enough to maintain a low center of gravity even when the support rod is at full extension with two filled 100ml burettes.
- Thread Integrity: We ensure the rod-to-base screw connection is precision-machined to prevent the "wobble" common in lower-priced alternatives.
- Direct Factory Inventory: Guaranteed availability of replacement Fisher Clamps and extra-long rods for specialized gas-measuring applications.
- Quality Assurance: Every batch of clamps is "grip-tested" on wet glass to ensure zero-slip performance under standard laboratory conditions.
