Supplied in a 500 ml glass bottle, it provides a convenient volume for routine differential staining of bacterial specimens in histology, microbiology and related life-science applications. The solution has a density of approximately 1 g\/cm³, supporting straightforward handling and dispensing at the bench during multi-step Gram procedures. Available from manufacturer Carl ROTH, this CombiStain preparation is positioned for laboratories that perform classical Gram differentiation as part of identification, teaching or quality-control microscopy. The glass packaging suits standard reagent storage and repeated access during staining sessions. Used as part of established Gram staining sequences, the solution helps visualise morphological and tinctorial differences between Gram-positive and Gram-negative organisms under the microscope. The 500 ml pack size balances day-to-day consumption with efficient inventory management for clinical, research and educational laboratories running regular staining series.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/histology-reagents-and-consumables\"\u003eHistology reagents \u0026amp; consumables\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/microscopy-and-histology\"\u003eMicroscopy \u0026amp; histology\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\u003eStorage temperature: +15 to +25 °C\u003c\/li\u003e\n\u003cli\u003eProduct type: Gram CombiStain solution\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-3N51-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDk1MjM3fGFwcGxpY2F0aW9uL3BkZnxhREE1TDJnek5TODVNalUwT0RZeU5qRTROalUwTDFOUVJWcGZNMDQxTVY5RlRpNXdaR1l8MWFlNzkzMjIyODMwYjQ2YzRlNGVjZDU2ZDVlYjY2MjJhN2QzOTYxZDc4NDg0MmFmMTA3ODEwNGRlNWRiMDgzZg\" 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-3N51-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzY5MTZ8YXBwbGljYXRpb24vcGRmfGFHRm1MMmc1TVM4NU1qTTJOalUzTVRFeE1EY3dMMU5FUWw4elRqVXhYMFJGWDBWT0xuQmtaZ3xhOTA5NjQyMDQ2M2UwYjE2YWIwYTdkZTFlN2IyM2I1ZjRjZGZhYmJhOTA0YTI4MjhiZDRhMjZlNGQ0Njg3ZjY5\" 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":58952073937228,"sku":"3N51.1","price":50.45,"currency_code":"EUR","in_stock":true},{"title":"1 l","offer_id":58952073969996,"sku":"3N51.2","price":90.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/3N51-1.jpg?v=1790399466","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/gram-combistain-solution-for-microscopy-500-ml-3n51-3n51","provider":"Luminix Health","version":"1.0","type":"link"}
