Tube Polytest (10) | Draeger

The Tube Polytest (10) is a high-precision chemical detection tube, primarily used for measuring the concentration of specific gases or chemicals in the air. It is designed for use in industrial and environmental safety monitoring, helping users detect and measure hazardous substances. The product is part of the Draeger Tube System, which combines the ease of use of colorimetric detection with the reliability of precision instruments.

1. Polytest Series

• The Polytest range of Draeger tubes is intended for the detection of a variety of gases or chemicals, often including toxic substances or gases with industrial applications, like solvents, vapors, or specific chemicals.

• The number "(10)" could be indicative of either a model version or a batch number, or it might refer to the specific concentration range that the tube can measure. This would typically need to be clarified based on the context of the tube type you are referring to.

2. Colorimetric Detection

• Colorimetric tubes are designed to change color in response to a chemical reaction between the substance being measured and the reagent inside the tube. The amount of color change corresponds to the concentration of the target gas or vapor.

• The reaction results in a visible gradient on the tube, allowing users to estimate the concentration of the gas.

3. Detection Range and Sensitivity

• Draeger tubes typically offer specific detection ranges for various gases. The Polytest (10) would come with detailed information on the exact gases it detects and its measurement range, often indicated in parts per million (ppm) or milligrams per cubic meter (mg/m³).

• The sensitivity of the tube is calibrated for precision, enabling users to detect low concentrations of gases accurately.

4. Ease of Use

• Simple operation: These tubes are designed for ease of use, often requiring only a small air sample drawn through the tube with a hand pump (like the Draeger Accuro or Draeger X-act pump).

• Quick results: Results are often visible within a few minutes of sampling, allowing for fast decision-making in hazardous environments.

5. Applications

• Industrial Safety: Used in factories, chemical plants, and other industrial settings to monitor air quality and ensure that workers are not exposed to hazardous levels of specific chemicals.

• Environmental Monitoring: Used in environmental testing to assess air quality, detect pollution, or measure the presence of certain gases in the atmosphere.

• Workplace Compliance: These tubes are often used for health and safety compliance, ensuring that workplaces meet occupational safety standards by monitoring specific chemicals in the air.

6. Calibration and Accuracy

• Each tube is pre-calibrated and provides a direct, visual reading of the concentration, so no additional calculations are typically required.

• Accuracy depends on factors like the volume of air sampled and the time taken for the reaction to occur.

7. Expiration and Storage

• Draeger tubes generally have a shelf life and must be stored properly to avoid degradation of the reagents inside. The packaging usually provides instructions on how to store them in optimal conditions.

• Tubes should be kept away from direct sunlight, moisture, and extreme temperatures to ensure reliable results.

8. Applications Examples

• Polytest (10) could be designed for specialized gases or chemicals such as:

  • Solvent vapors (e.g., acetone, benzene, toluene)

  • Acidic gases (e.g., hydrogen chloride)

  • Toxic industrial chemicals (e.g., hydrogen sulfide, ammonia)

  • Others based on the specific tube.
