With a 0.002% (20 ppm) detectable limit, a 3-year shelf life, and a 32–104°F operating range, this tube is well suited for process and leak monitoring relative to the 1,000 ppm TLV-STEL guideline, noting that toluene, hexane, and trichloroethylene can produce similar stains and lead to higher readings, while ethyl alcohol does not affect accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/n-Butane_Tube_No._NX114_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":49255914242300,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX114-Tube-box-Combo-2024.png?v=1771746160","url":"https:\/\/samplingdepot.com\/products\/nextteq-n-butane-tube-no-nx114","provider":"Sampling Depot","version":"1.0","type":"link"}
