Measuring Cylinder
Product Code : SCL-CLE-11926
The StemAids Measuring Cylinder (Graduated Cylinder) is a foundational laboratory instrument engineered for the precise measurement of liquid volumes. Characterized by a tall, narrow profile to minimize volumetric error, it is manufactured from high-clarity Borosilicate Glass 3.3 to ensure chemical neutrality and thermal stability. Available in various accuracy classes and base configurations, it serves as the primary tool for reagent preparation and displacement experiments in all scientific disciplines.

Key Pedagogical & Laboratory Outcomes
- Volumetric Interface: Facilitates student understanding of Quantitative Measurement. Learners identify how the narrow internal diameter allows for a more sensitive reading compared to a wide-mouth beaker.
- Density Quantification: Enables "Volume by Displacement"; learners apply the cylinder to calculate the volume of irregular solids by measuring the rise in liquid level (Archimedes' Principle).
- Concentration Analysis: Supports the analysis of "Solution Dilution"; students evaluate the mixing of solvents and solutes, utilizing the permanent scale to achieve specific molarities.
- Accuracy Evaluation: Allows students to evaluate the concept of "Parallax Error"; learners practice aligning their line of sight with the bottom of the meniscus to ensure data integrity.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density packaging. Each cylinder is individually bubble-wrapped and nested in heavy-duty cardboard dividers to protect the pouring spout and base from mechanical fracture during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and batch-specific calibration certificates for Class A units.
- Durability: The Borosilicate 3.3 glass is stress-relieved in a lehr, ensuring the cylinder can withstand repeated wash cycles and chemical exposure without losing optical clarity or scale legibility.
Direct OEM Sourcing Advantages
Procuring StemAids Measuring Cylinders directly ensures vertical manufacturing control:
- Precision Calibration: Direct oversight ensures the graduation marks are laser-aligned to the internal volume, meeting the strict tolerances required by ISO 4788.
- Anti-Roll Bases: We provide hexagonal bases as a standard option to prevent the cylinder from rolling and breaking if tipped over on the laboratory bench.
- Direct Factory Inventory: Guaranteed availability of the full volumetric range, including large 2000ml cylinders for industrial-scale reagent preparation.
- Quality Assurance: Every batch is "spout-tested" to ensure a clean, drip-free pour, preventing the loss of analyte during transfer.
