Tube Toluene 50/a (10) | Draeger

The Dräger Tube Toluene 50/a (10) is a detection tube used to measure the concentration of toluene vapor in the air. This tube works in conjunction with a Dräger pump (such as the Dräger 100 or 3000) and provides a quick and reliable method for detecting toluene levels in various environments.

Key Features:

• Target Substance: Toluene (C₆H₅CH₃), a common aromatic hydrocarbon solvent used in industrial applications such as paint thinners, adhesives, coatings, and chemical production.

• Detection Range:

  • The Dräger Tube Toluene 50/a (10) typically has a range of detection from 10 ppm to 50 ppm of toluene vapor in the air.

  • It is designed to give accurate readings within this concentration range.

• Measurement Principle:

  • The tube uses a color change reaction to indicate the concentration of toluene in the air.

  • When air is drawn through the tube, the chemical reagents inside react with the toluene vapor, causing a color change (often from yellow to a darker color).

  • The length of the color change is proportional to the amount of toluene detected, which can then be correlated to a concentration value based on the scale printed on the tube.

• Duration: The test typically takes about 1-3 minutes to complete, providing a quick result on-site.

• Volume: The air sample is drawn through the tube using a 100 mL air sample with a Dräger pump, ensuring consistent and accurate sampling.

• Single-use: Dräger tubes are disposable and meant for one-time use, making them convenient for on-the-spot testing without the need for cleaning or reuse.

Typical Applications:

• Industrial Hygiene: Used in environments like manufacturing plants, laboratories, and warehouses where toluene is used or produced, such as in solvent applications, paint, coating, and chemical processes.

• Workplace Safety: Ensures that toluene levels do not exceed occupational exposure limits, protecting workers from health risks associated with inhalation of this solvent.

• Environmental Monitoring: Used in areas where toluene may be released into the atmosphere, ensuring that environmental regulations are met.

Benefits:

• Easy to Use: Simple and quick testing procedure, providing results in real time.

• High Accuracy: The colorimetric method offers a direct and reliable measurement of toluene concentrations.

• Portable: Small and easy to carry, making it ideal for on-site air quality monitoring in various industrial or environmental settings.

• Cost-effective: A more affordable option for periodic monitoring compared to continuous or more complex instruments.

Sensitivity & Safety:

• The Dräger Toluene Tube 50/a (10) is designed to be highly sensitive to toluene vapors in the specified concentration range.

• Toluene exposure can have harmful effects on health, including dizziness, headaches, and neurological damage at higher concentrations, making monitoring of exposure levels critical.

General Procedure:

1. Insert the tube into a Dräger pump.

2. Draw the air sample (usually 100 mL) through the tube using the pump.

3. Observe the color change in the tube. The extent of the color change correlates to the concentration of toluene in the air.

4. Read the result on the scale printed on the tube to determine the concentration of toluene.

Conclusion:

The Dräger Tube Toluene 50/a (10) is an effective and reliable tool for measuring the concentration of toluene vapors in ambient air, ensuring that workers and the environment are kept safe from hazardous exposure to this solvent. It’s widely used in various industries to maintain workplace safety and environmental compliance.
