{"product_id":"nextteq-benzene-tube-no-nx111m","title":"Nextteq Benzene Tube No. NX111M","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Nextteq Benzene Tube No. NX111M provides direct measurement of benzene over three ranges—4–100 ppm, 2–50 ppm, and 1–25 ppm—using 1, 2, or 4 pump strokes and a clear white-to-greenish-brown color change, with temperature correction required and single- or four-stroke readings converted using a simple formula. With a 0.2 ppm detectable limit at 400 mL, a 2-year shelf life, and a 32–104°F operating range, this tube is well suited for workplace and process monitoring relative to the very low 0.02 ppm TLV-TWA guideline, noting that toluene and xylene can produce yellowish-brown stains and higher readings, while carbon monoxide and hexane can cause the reagent to change color and obscure the stain endpoint.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Benzene_Tube_No._NX111M_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":49255893795068,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX111M-Tube-box-Combo-2024.jpg?v=1771746135","url":"https:\/\/samplingdepot.com\/products\/nextteq-benzene-tube-no-nx111m","provider":"Sampling Depot","version":"1.0","type":"link"}
