Nessler Tube

The Nessler tube is made of borosilicate glass, used primarily for colorimetric analysis.

Its main characteristics are:

Material: It is made of borosilicate glass, known for its low thermal expansion and resistance to thermal shock.

Capacity and Graduations: The cylinder has a nominal capacity of 100 mL and features a graduation mark at 50 mL, as well as a temperature indication of 27°C.

Design: This is an optically flat-bottomed cylinder with a pouring spout, designed for accurate visual comparisons of color and turbidity between solutions.

Use: Nessler tubes are commonly used in laboratories for colorimetric analysis, such as comparing APHA color or detecting dissolved substances via color changes with specific reagents (e.g., Nessler’s reagent for ammonia).

Accuracy: Class A Nessler tubes, like this one, are manufactured to high precision standards to ensure reliable…
