Tube Phosphine 25/a (10) | Draeger

The Draeger Tube Phosphine 25/a (10) is a gas detection tube designed to measure the concentration of phosphine (PH₃) in the air. It is part of Draeger's line of gas detection tubes that are used for quick, reliable, and accurate measurement of various gases in the environment.

Product Details:

• Type of Gas: Phosphine (PH₃)

• Measurement Range: 0.1 - 25 ppm (parts per million) of phosphine, depending on the specific model and use.

• Tube Type: The Draeger tube is typically a glass tube filled with a chemical reagent that reacts with the target gas (in this case, phosphine) to produce a color change. The extent of the color change indicates the concentration of the gas present in the air.

• Detection Method: The tube is used in conjunction with a Draeger pump (such as the Draeger Accuro pump). Air is drawn through the tube using the pump, and the color change is used to determine the gas concentration.

• Sensitivity: The specific sensitivity is 10 ppm, which means the tube can detect low to moderate levels of phosphine in air.

• Duration of Test: Typically, the reaction in the tube will take place within a few minutes, depending on the level of phosphine.

• Application: This tube is often used in environments where phosphine is a potential hazard, such as in agriculture (e.g., grain fumigation), industrial settings, and laboratories.

• Shelf Life: Draeger gas detection tubes typically have a shelf life of 1 to 3 years, but this can vary based on storage conditions.

Features:

• Quick and Simple: Draeger tubes are known for their ease of use. No complex calibration or setup is needed. Just insert the tube into the pump, draw a sample, and observe the color change.

• Portable: The system is portable, making it useful for fieldwork, inspections, or emergency situations.

• Highly Accurate: Draeger's colorimetric detection method provides highly accurate measurements with low detection limits.

Safety Considerations:

• Phosphine is a toxic and flammable gas, often used in industrial and agricultural applications. It can be dangerous at high concentrations and poses health risks through inhalation.

• Protective Equipment: It’s recommended to wear appropriate personal protective equipment (PPE), such as gloves and goggles, when working with or testing for phosphine.
