{"product_id":"potassium-bromide-cp19-cp19","title":"Potassium bromide, for IR spectrometry, 50 g, plastic","description":"\u003cp\u003ePotassium bromide is an inorganic salt prepared for infrared spectrometry, with CAS number 7758-02-3 and empirical formula KBr. It has a molar mass of 119,00 g\/mol, a density of 2,75 g\/cm³ and a boiling point of 1435 °C. In IR work it serves as a transparent matrix and window material for preparing solid samples by the classic KBr pellet technique, allowing transmission spectra of powders and crystalline substances to be recorded with minimal matrix interference in the mid-infrared region. from manufacturer Carl ROTH is convenient for spectroscopy laboratories that routinely press pellets or maintain IR-grade halide stocks. High thermal stability and defined physical constants support reproducible sample preparation and instrument calibration routines. EG nr. 231-830-3 assists laboratory inventory and safety documentation. This grade is positioned for carrier and matrix use in infrared spectroscopy rather than general wet-chemical applications.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/photometers-and-spectrophotometers\"\u003ePhotometers \u0026amp; spectrophotometers\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/spectroscopy-and-photometry\"\u003eSpectroscopy \u0026amp; photometry\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSuitability for IR spectrometry: complies\u003c\/li\u003e\n\u003cli\u003eH2O (λ = 3775-3050 \/ 1760-1520 cm-1): ≤0.15\u003c\/li\u003e\n\u003cli\u003eCH-compounds (λ = 3050-2750 cm-1): ≤0.004\u003c\/li\u003e\n\u003cli\u003eOthers (λ = 4000-400 cm-1): ≤0.020\u003c\/li\u003e\n\u003cli\u003ed10: ≤150 µm\u003c\/li\u003e\n\u003cli\u003ed50: ≤250 µm\u003c\/li\u003e\n\u003cli\u003ed90: ≤500 µm\u003c\/li\u003e\n\u003cli\u003eCAS number: 7758-02-3\u003c\/li\u003e\n\u003cli\u003ePack sizes: 100 g, 50 g\u003c\/li\u003e\n\u003cli\u003eEG nr.: 231-830-3\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: KBr\u003c\/li\u003e\n\u003cli\u003eMolar mass: 119,00 g\/mol\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-CP19-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNTg4NXxhcHBsaWNhdGlvbi9wZGZ8YUdWaEwyZ3lNQzg1TWpVME9UYzJPVFEyTWpBMkwxTlFSVnBmUTFBeE9WOUZUaTV3WkdZfGExZGUzN2I2M2M4NDhlZDQ4NjlkN2RiMjQ3MjVjMWJmOTE5M2RhMjZjYTAwYTk2MDFiYTdmZjAyMzkzZDkzOWU\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-CP19-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzc3MjB8YXBwbGljYXRpb24vcGRmfGFHTmhMMmczTVM4NU1qSXpNVFkwT0RVME16QXlMMU5FUWw5RFVERTVYMFJGWDBWT0xuQmtaZ3w5Yzk3YjRjMGQyMWQxNTBkNjBiZmViZGQzY2YwZGNkOWU1YzczODM5YTIwZTA4YjM1NGNkMjk4MTgxMDIxNmE3\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"50 g \/ 1 piece","offer_id":56180073005388,"sku":"CP19.2","price":117.2,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56180073038156,"sku":"CP19.2","price":111.34,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56180073070924,"sku":"CP19.2","price":105.48,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56180073103692,"sku":"CP19.1","price":220.4,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56180073136460,"sku":"CP19.1","price":209.38,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56180073169228,"sku":"CP19.1","price":198.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/CP19-1000Wx1000H_df6eb1f7-6aff-4f6e-bae4-2b8d05039cb1.jpg?v=1766447733","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/potassium-bromide-cp19-cp19","provider":"Luminix Health","version":"1.0","type":"link"}
