Lovibond® Nessler Tubes

Lovibond® Nessler Tubes are precision glass cylinders designed for accurate visual color comparison and quantitative analysis in water quality testing, chemical analysis, and environmental monitoring. These tubes are commonly used in Nesslerization methods for determining ammonia, turbidity, and other colorimetric parameters, where visual comparison against standards is required.

Manufactured from high-quality optical glass, Lovibond Nessler Tubes ensure excellent clarity, consistent optical path length, and reliable analytical performance. Available in different lengths and configurations, including models with plungers, they allow precise adjustment of the optical column height for enhanced measurement sensitivity and reproducibility.

Key Features

• High optical clarity: Premium glass ensures accurate visual color comparison.
• Precision measurement: Uniform internal diameter provides consistent optical path length.
• Adjustable optical path (plunger models): Enables precise column height adjustment for enhanced sensitivity.
• Durable construction: Chemically resistant glass suitable for routine laboratory use.
• Versatile applications: Compatible with Lovibond color comparators and Nesslerization methods.
• Reliable reproducibility: Ideal for standardized water quality and chemical testing protocols.

Applications

• Water quality analysis (ammonia, nitrogen, chlorine, and turbidity)
• Environmental monitoring
• Wastewater and drinking water testing
• Chemical laboratory colorimetric analysis
• Educational and research laboratories
• Industrial process monitoring

Ordering Information

Specifications

Nessler tubes operate based on the principle of colorimetric comparison. The sample is placed in the tube and compared visually against standard solutions or comparator references. When plungers are used, they allow adjustment of the liquid column height to match the intensity of the reference standard, enabling accurate quantitative determination of analyte concentration.
