Description
The Nextteq Butyl Acetate Tube No. NX184M provides direct measurement of butyl acetate from 0.01–1.0% using two 100 mL pump strokes (200 mL total) and a clear orange-to-brownish-green color change, with the tube scale calibrated on methyl ethyl ketone and butyl acetate concentrations determined via a simple conversion chart. With a 10 ppm detectable limit, a 3-year shelf life, and a 32–104°F operating range, this tube is well suited for workplace and process monitoring relative to the 50 ppm TLV-TWA and 150 ppm TLV-STEL guidelines, noting that most organic gases and vapors (except halogenated hydrocarbons) can produce similar stains and higher readings, while acetylene at 3% and propane at 0.2% can turn the entire reagent brown.
