Tube Phosgene 0.25/c (10) | Draeger

Key Features

• Low-range detection: designed to detect phosgene at low concentrations (suitable for 0.25 ppm-level measurement).

• Colorimetric, single-step readout: visible color change along a graduated scale for direct reading of concentration.

• Quick field results: rapid reaction time—simple pump sampling, no laboratory required.

• Portable and rugged: glass tube format, individually packaged for protection and traceability.

• Pack quantity: 10 tubes per pack (hence “(10)” in the product name).

• Compatibility: works with standard Dräger manual pumps and many third‑party piston or bellows pumps (check pump stroke volume).

• Typical shelf life / storage: store in a cool, dry place away from sunlight—typical shelf life ~2–3 years unopened.

Typical Technical Specifications

• Detection range (nominal): 0.05 – 0.5 ppm or calibrated for 0.25 ppm reading (tube name indicates 0.25 concentration marker) — optimized around 0.25 ppm (typ.).

• Detection principle: colorimetric reagent reacts with phosgene producing a colored stain whose length correlates with concentration.

• Sampling volume / strokes: usually one or multiple pump strokes depending on pump stroke volume; example: 1 × 1 L stroke or 10 × 100 mL strokes — follow tube instructions for exact stroke count.

• Reaction time: reading appears immediately but final stabilization / recommended read time typically ~1–10 minutes after sampling (typ.).

• Tube length / diameter: standard Dräger tube dimensions (glass) — exact dimensions vary by tube type.

• Temperature operating range: typically 0–40 °C (verify).

• Humidity tolerance: many colorimetric tubes are affected by very high humidity; check tube-specific cross‑sensitivities.

• Accuracy & uncertainty: colorimetric tubes have an established accuracy band (for example ±20–30% at rated concentration) — see manufacturer datasheet for precise performance metrics.

Typical Applications

• Emergency response and first‑responder rapid screening.

• Industrial monitoring in chemical plants, chemical handling and storage areas.

• Leak detection and verification after maintenance/repair.

• Short‑term area checks and spot measurements for worker safety.

• Environmental/incident sampling where instrument-grade real-time monitors are not available.

Safety, Limitations & Interferences

• Cross-sensitivities: other chlorinated or reactive gases may cause interference; refer to manufacturer cross-sensitivity list.

• Limitations: colorimetric tubes give approximate quantitative results — not a substitute for continuous electronic monitors for formal compliance monitoring.

• Interfering factors: extreme humidity, very high/low temperatures, presence of particulate matter or aerosols can affect accuracy.

• Waste: used tubes contain chemical reagents — handle and dispose of according to local hazardous waste rules.

• Not for personal protection: tubes are sampling/measurement devices, not respirators.

Packaging & Ordering Information

• Packaging: box of 10 tubes (individually sealed).

• Typical label elements: product name, target gas, detection range, number of strokes/volume, lot number, expiry date, storage instructions.

• Accessories (sold separately): compatible manual pumps, tube tip breakers, calibration solutions for verification, protective case.

Certifications & Quality

• Manufactured under Dräger quality management systems.

• Each tube lot usually undergoes QA testing and is identified by lot number and expiry date.

• Suitable for field use by trained personnel; follow the manufacturer’s instructions for use (IFU).
