{"product_id":"nextteq-1-3-butadiene-tube-no-nx113m","title":"Nextteq 1,3-Butadiene Tube No. NX113M","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Nextteq 1,3-Butadiene Tube No. NX113M provides direct measurement of 1,3-butadiene over two ranges—5–100 ppm with one 100 mL pump stroke and 2.5–50 ppm with two strokes—using a clear pale-yellow-to-pale-blue color change, with two-stroke readings converted using a simple ½× formula. With a 0.5 ppm detectable limit at 200 mL, a 1-year shelf life, and a 32–104°F operating range, this tube is well suited for workplace and process monitoring relative to the 2 ppm TLV-TWA guideline, noting that esters, alcohols, and ketones can produce similar stains and higher readings, while aromatic hydrocarbons above C3 may turn the entire reagent pale brown.\u003c\/p\u003e","brand":"Sampling Depot","offers":[{"title":"Default Title","offer_id":49255882129660,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX113M-Tube-box-Combo-2024.jpg?v=1771746159","url":"https:\/\/samplingdepot.com\/products\/nextteq-1-3-butadiene-tube-no-nx113m","provider":"Sampling Depot","version":"1.0","type":"link"}
