With a 3-year shelf life, a narrow 59–77°F operating range, and calibration by standard gas cylinder method, this tube is well suited for workplace and process monitoring relative to the 1 ppm TLV-TWA guideline, noting that acetylene and ethylene can cause lower readings in coexistence, while hydrogen chloride below 500 ppm and chlorine below 50 ppm do not affect accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Benzyl_Chloride_Tube_No._NX221L__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":49255897137404,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX221L-Tube-box-Combo-2024.jpg?v=1771746206","url":"https:\/\/samplingdepot.com\/products\/nextteq-benzyl-chloride-tube-no-nx221l","provider":"Sampling Depot","version":"1.0","type":"link"}
