With a 2 ppm detectable limit, 2-year shelf life, 32–104°F operating range, and temperature correction guidance, this tube is well suited for workplace and process monitoring relative to the 20 ppm TLV-TWA guideline, noting that alcohols and toluene can produce similar stains or affect readings in coexistence.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Benzaldehyde_Tube_No._NX151__Data_Sheet.pdf?v=1783343335\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eData Sheet (PDF)\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Sampling Depot","offers":[{"title":"Default Title","offer_id":49255879246076,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX151-Tube-box-Combo-2024-no-tube_1.png?v=1771746177","url":"https:\/\/samplingdepot.com\/products\/nextteq-1-butanol-tube-no-nx151","provider":"Sampling Depot","version":"1.0","type":"link"}
