Description
The Nextteq 2-Bromopropane Tube No. NX180H provides direct measurement of 2-bromopropane from 10–500 ppm using a single 100 mL pump stroke and a clear white-to-reddish-orange color change, with the tube scale calibrated on methyl bromide and 2-bromopropane concentrations determined via a simple conversion method. With a 3-year shelf life when stored under refrigerated conditions (32–50°F), a narrow 59–77°F operating range, and calibration by gas chromatography, this tube is well suited for workplace and process monitoring of 2-bromopropane, even though no TLV value is currently listed (TLV: N/A), noting that halogens, halogenated hydrocarbons, trichloroethylene, and tetrachloroethylene can produce similar stains and lead to higher readings.
