Visual Comparison & Colorimetric Excellence

The Nessler Cylinder (Class B) is a specialized piece of laboratory glassware designed for colorimetric analysis and Nesslerization. Its tall, narrow profile and flat, optically clear base allow light to pass vertically through the sample, providing the most accurate visual comparison against standard reference solutions.

Whether you are conducting ammonia testing, limit tests for impurities, or general water quality assessments, these cylinders provide the durability and clarity required for routine laboratory workflows.

Key Technical Features

• Premium Borosilicate 3.3 Glass: Engineered for high thermal shock resistance and superior protection against chemical corrosion from acids and reagents.
• Class B Accuracy: Manufactured to meet standardized tolerances (typically ±0.8ml to ±1.6ml depending on size), offering a cost-effective solution for routine volumetric observations.
• Permanent Enamel Graduations: High-contrast white or amber markings at standard intervals (e.g., 25ml and 50ml) for precise volume measurement.
• Optically Clear Flat Base: The ground flat bottom ensures stability on lab benches and distortion-free light transmission during vertical color checks.
• Uniform Wall Thickness: Robust construction reduces the risk of breakage and ensures consistency across multiple cylinders in a set.

Common Laboratory Applications

• Nessler’s Test: Detection of ammonia and ammonium ions in environmental and industrial water samples.
• Limit Tests: Semi-quantitative analysis for identifying traces of inorganic impurities as per Pharmacopoeia standards.
• Wastewater Analysis: Visual assessment of turbidity and color intensity in chemical testing facilities.
• Academic Research: A staple in chemistry education for teaching the principles of visual titration and colorimetry.
