{"product_id":"nextteq-benzene-tube-no-nx111vh","title":"Nextteq Benzene Tube No. NX111VH","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Nextteq Benzene Tube No. NX111VH is specifically designed for measuring benzene in the presence of other aromatic hydrocarbons, providing direct measurement from 5–300 ppm using a single 100 mL pump stroke and a clear white-to-greenish-brown color change, with temperature correction required for accurate readings. With a 3 ppm detectable limit, 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 hexane at high concentrations can turn the entire reagent dark grey.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Benzene_Tube_No._NX111VH_Data_Sheet.pdf?v=1783343336\" 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":49255895531772,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX111VH-Tube-box-Combo-2024-no-tube_1.png?v=1771746160","url":"https:\/\/samplingdepot.com\/products\/nextteq-benzene-tube-no-nx111vh","provider":"Sampling Depot","version":"1.0","type":"link"}
