{"product_id":"methylene-blue-solution-3n57-3n57","title":"Methylene blue solution","description":"\u003cp\u003eMethylene blue solution is a staining reagent prepared for microscopy, including Gram staining and related histological work. The formulation is supplied in a 500 ml glass bottle and shows a density of approximately 1 g\/cm³ together with a boiling point of 100 °C, properties that support routine bench handling in life-science laboratories. This preparation from manufacturer Carl ROTH is intended for consistent dye performance during microscopic examination of specimens in research, teaching, and diagnostic staining workflows. Its aqueous character fits common differential staining sequences used in histology and microbiology without requiring complex on-site reconstitution. At a unit weight of 0,785 kg, the pack size suits regular laboratory consumption for slide preparation and protocol development. Categories linked to the product cover life science, histology and microscopy, staining, and Gram staining, underscoring its role in classical and contemporary staining techniques. Laboratories can place the solution directly into established microscopy protocols where a reliable methylene blue dye is required for contrast and structural visualisation.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/microscopy-stains-and-staining-solutions\"\u003eMicroscopy stains \u0026amp; staining solutions\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/dyes-stains-and-indicators\"\u003eDyes, stains \u0026amp; indicators\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack sizes: 500 ml, 1 l\u003c\/li\u003e\n\u003cli\u003eDensity: ~1 g\/cm³\u003c\/li\u003e\n\u003cli\u003eBoiling point: 100 °C\u003c\/li\u003e\n\u003cli\u003eWeight: 0,785 kg\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 41116113\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-3N57-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDk1NDc5fGFwcGxpY2F0aW9uL3BkZnxhR1poTDJneVpTODVNalUwT0RZeU5EZzNOVGd5TDFOUVJWcGZNMDQxTjE5RlRpNXdaR1l8YjAzZmZjNWFjN2IzMmRhYTI3MjMyOGI4MzVlMWE1ZTEwNzhiYWZjMzQwYmNjY2FkMDBlMjgxOWI4MjExYWMxMg\" 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-3N57-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzY5MzB8YXBwbGljYXRpb24vcGRmfGFEbGpMMmc0TWk4NU1qTTJOalU1T0RNd09ERTBMMU5FUWw4elRqVTNYMFJGWDBWT0xuQmtaZ3xmMThiOGQ0NmM3ZmRjOWQ3ZmI3MTExNmJlY2RlNmE0YzgzMGI3MTY2ZTI3MzBmYTBmZmFjZmYxM2Q3MTg3ZjNm\" 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":"500 ml","offer_id":58952074690892,"sku":"3N57.1","price":50.45,"currency_code":"EUR","in_stock":true},{"title":"1 l","offer_id":58952074723660,"sku":"3N57.2","price":90.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/3N57-1.jpg?v=1790399476","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/methylene-blue-solution-3n57-3n57","provider":"Luminix Health","version":"1.0","type":"link"}
