With a 3-year shelf life, a narrow 59–77°F operating range, and calibration by diffusion tube method, this tube is well suited for workplace and process monitoring of n-butyric acid, even though no TLV value is currently listed (TLV: N\/A), noting that sulfur dioxide, acetic acid, and chlorine can produce similar or off-color stains and higher readings, while nitrogen dioxide at 300 ppm 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\/n-Butyric_Acid_Tube_No._NX102__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":49255917584636,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX102-Tube-box-Combo-2024.png?v=1771746137","url":"https:\/\/samplingdepot.com\/products\/nextteq-n-butyric-acid-tube-no-nx102","provider":"Sampling Depot","version":"1.0","type":"link"}
