Description
The Nextteq Benzaldehyde Tube No. NX151 provides direct measurement of benzaldehyde using three 100 mL pump strokes (300 mL total) and a clear yellow-to-pale-blue color change, with the tube scale calibrated on Ethyl Cellosolve and benzaldehyde concentrations determined via a lot-specific conversion chart available from Nextteq or your distributor. With a 2-year shelf life, a strictly controlled 68°F operating temperature, and calibration by gas chromatography, this tube is well suited for workplace and process monitoring of benzaldehyde, even though no TLV value is currently listed (TLV: N/A), noting that alcohols, ethers, ketones, aromatic and aliphatic hydrocarbons, and halogenated hydrocarbons can produce similar stains and lead to higher readings.
