Glass Burette 50ml
Product Code : SCL-CLE-11934
The StemAids 50ml Glass Burette is the standard analytical instrument for the high-precision delivery of liquid titrants. Featuring a uniform internal bore and a long, slender body, it allows for the measurement of liquids with a level of accuracy that graduated cylinders cannot achieve. This specific model is designed for institutional use, offering a balance of durability, chemical resistance, and clear legibility. Manufactured to ISO 385 standards, it is an indispensable tool for University Chemistry, Food Quality Control, and Pharmaceutical analysis.

Key Pedagogical & Laboratory Outcomes
- Volumetric Interface: Facilitates student mastery of Quantitative Analysis. The linear scale allows learners to identify the precise volume of a reagent consumed to neutralize an analyte, providing the data necessary for concentration calculations.
- Flow Quantification: Enables controlled Drop-wise Addition; learners apply the burette to find the "equivalence point" of a reaction, where a single drop can signify a complete chemical change.
- Error Analysis: Supports the analysis of "Reading the Meniscus"; students evaluate the impact of parallax error and learn to interpolate between 0.1ml markings to estimate volume to the nearest 0.01ml.
- Durability Evaluation: Allows labs to evaluate the longevity of Borosilicate 3.3; the glass is resistant to the "clouding" and "etching" typically caused by long-term exposure to strong alkaline titrants like NaOH.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-impact packaging. Burettes are exceptionally long and prone to bending stress; each unit is packed in a rigid cardboard tube or high-density foam insert to ensure zero-breakage during maritime or air transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and batch-specific calibration certificates for Class AS units.
- Quality Standard: Every burette is stress-relieved in a computer-controlled lehr to ensure that the glass is free of internal strain, preventing spontaneous fracture.
Direct OEM Sourcing Advantages
Procuring the StemAids Glass Burette directly ensures vertical manufacturing control:
- Internal Bore Precision: Direct oversight of the drawing process ensures the internal diameter is perfectly uniform throughout the length of the tube, which is critical for linear accuracy.
- Individually Tested Tips: We ensure the delivery tips are precision-ground and fire-polished to provide a standardized drop volume and a smooth, consistent flow.
- Direct Factory Inventory: Guaranteed availability of the full range of 50ml burettes with various stopcock configurations (Glass, PTFE, or Rota Flow).
- Quality Assurance: Every Class AS burette is gravimetrically tested across the entire scale to ensure it meets or exceeds ISO 385 volumetric tolerances.
