6728961 (1 to 15 ppm), 6728241 (25 to 500 ppm).

Q: What is the lowest range Draeger tube for Ethylene oxide?

6728961, 1 to 15 ppm, 20 strokes.

Q: What is the OSHA exposure limit for Ethylene oxide?

OSHA PEL [1910.1047] TWA 1 ppm 5 ppm [15-minute Excursion]; NIOSH REL Ca TWA <0.1 ppm (0.18 mg/m³) C 5 ppm (9 mg/m³) [10-min/day]; IDLH Ca [800 ppm] (NIOSH Pocket Guide).

Q: Which pump reads Draeger Ethylene oxide tubes?

Source: NIOSH Pocket Guide to Chemical Hazards, Ethylene oxide (OSHA PEL from 29 CFR 1910.1000 Table Z as listed there). TWA = 8-hour time-weighted average, ST = short-term (15-minute), C = ceiling, Ca = NIOSH potential occupational carcinogen. NIOSH physical description: Colorless gas or liquid (below 51°F) with an ether-like odor.

Draeger short-term tubes are read on a Draeger accuro or X-act 5000 tube pump. Per the handbook (pp. 28–29), Draeger tubes and Draeger pumps are matched at the factory and form a single unit; other makers' pumps and tubes are not interchangeable with them. All Draeger tubes A–Z.
