Our High Borosilicate Glass Colorimetric Tubes are precision-manufactured analytical vessels designed for visual color comparison, colorimetric analysis, and the preparation of standard color reference series. Made from premium transparent borosilicate glass, these tubes provide excellent optical clarity, chemical resistance, and thermal stability, ensuring reliable and consistent analytical results in laboratory, educational, and industrial applications.

Key Features

Premium Borosilicate Glass Construction
Manufactured from high-quality borosilicate glass, offering outstanding transparency, excellent resistance to chemicals, and enhanced durability for long-term laboratory use.

Optimized Color Comparison Design
The slender cylindrical body with a flat-bottom structure allows clear vertical observation of solution color intensity, improving the accuracy and consistency of visual color assessments.

Precision Graduation Marks
Each tube is equipped with standardized graduation lines to facilitate accurate volume alignment and ensure reproducible comparison conditions during analytical procedures.

Ideal for Standard Color Series Preparation
Commonly used in sets of 6, 12, or more tubes to prepare and maintain standard color reference solutions, enabling reliable comparative colorimetric analysis across multiple samples.

Compatible with Ground Glass Stoppers
Can be fitted with precision ground glass stoppers for secure sample storage. For volatile solutions or long-term preservation, the joint may be additionally sealed with paraffin wax to minimize evaporation and maintain sample integrity.

Robust Laboratory Performance
Featuring thickened glass walls for enhanced mechanical strength and durability, these tubes are suitable for routine laboratory testing, quality control procedures, environmental monitoring, and industrial analytical applications.
