{"product_id":"nextteq-1-3-butadiene-tube-no-nx113l","title":"Nextteq 1,3-Butadiene Tube No. NX113L","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Nextteq 1,3-Butadiene Tube No. NX113L is a high-sensitivity detector tube that measures 1,3-butadiene over two ranges—0.5–10.0 ppm with one 100 mL pump stroke and 0.1–2.0 ppm with four strokes—using a clear pink-to-white color change, with single-stroke readings converted using a simple 5× formula. With an ultra-low 0.02 ppm detectable limit at 400 mL, a 3-year shelf life, and a 32–104°F operating range, this tube is ideal for low-level workplace monitoring relative to the 2 ppm TLV-TWA guideline, noting that hydrogen sulfide and isobutylene can produce similar stains and higher readings, and that ammonia can make the stain endpoint difficult to discern.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/1_3-Butadiene_Tube_No._NX113L_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":49255881474300,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX113L-tube-box-2024_combo.jpg?v=1771746159","url":"https:\/\/samplingdepot.com\/products\/nextteq-1-3-butadiene-tube-no-nx113l","provider":"Sampling Depot","version":"1.0","type":"link"}
