Stoppered Colorimetric Tube, 100 mL / 50 \~ 100 mL Scale Range (CAT#: STEM-AL2-5974-ZJF)

The Stoppered Colorimetric Tube is designed for visual color comparison and approximate solution-concentration analysis. Matched tubes can be filled with test and reference solutions and compared under similar illumination conditions. The source identifies borosilicate glass construction with low thermal expansion for the series. This configuration has a nominal capacity of 100 mL. The listed scale range and tolerance provide the source-specified volumetric reference for this tube size. A stopper supports covered handling of prepared solutions during comparison procedures. The tubular format supports side-by-side visual observation of color intensity between samples. The product is intended for teaching, analytical chemistry, water testing, and other routine visual colorimetric workflows.
