Tabung Stopper, Pembanding Warna (Nessler Colometric Tube), 25 ml
Rp123.00
Our Nessler tube is a specialized laboratory cylinder with a flat bottom, used for colorimetric analysis (comparing the color intensity of a liquid sample against a known standard).
Key Features:
Material: Made from high-quality borosilicate glass (like Pyrex) for chemical resistance and optical clarity.
Viewing Method: Observations are typically made by looking down through the top of the tube against a white background to maximize the light path through the liquid.
Graduations: Common sizes include 50mL and 100mL, often with a single graduation mark for precise volume filling.
Common Applications:
Water Quality Testing: Used for the "Nesslerization" method to detect low concentrations of Ammonia in water.
Hazen/APHA Color Scale: Determining the "yellowness" of liquids (e.g., wastewater or chemicals) compared to platinum-cobalt standards.
Visual Colorimetry: Simple field tests where electronic spectrophotometers are unavailable.
