Used extensively by forensic professionals, this lipid-soluble dye binds selectively to sebaceous, greasy, or sticky residues on non-porous surfaces. The compound produces a deep blue-black coloration that maximizes visual contrast against light-colored substrates. Investigators rely on this targeted solution to rescue intelligence from wet glass, plastics, and metallic items.\u003c\/p\u003e\n\u003cp\u003eEngineered for rigorous laboratory processing, this pre-mixed liquid eliminates the hazards of manual dye dissolution. By providing a standardized working strength, technicians ensure court-admissible enhancements with consistent batch-to-batch reliability. When incorporated into standard forensic workflows, the solution attacks the fatty matrix where traditional cyanoacrylate fuming or dusting powders fail. This creates a highly visible, stable reaction that is easily captured during high-resolution photographic documentation.\u003c\/p\u003e\n\u003cp\u003eTo prevent sample degradation, the treated evidence must be carefully monitored and rinsed with water to remove background interference. Maintaining strict control over the immersion time ensures the lipid structures remain brightly colored while the surrounding substrate clears. For optimal laboratory safety, this chemical reagent should always be applied within a certified fume hood. Technicians must utilize appropriate personal protective equipment to prevent heavy staining.\u003c\/p\u003e\n\u003ch2\u003eAvailable Sizes and Configurations\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSKU\u003c\/th\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eVolume\u003c\/th\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFormat\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePF-SB-500mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e500 mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePF-SB-1L\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e1 L\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eLipid-Sensitive Latent Print Reagent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eTarget Material\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eGreasy, oily, or sebaceous residues\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eApplication Surface\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eNon-porous items (glass, plastic, metal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDeveloped Color\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDeep Blue-Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePreparation Requirement\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eReady to use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eFor specialized forensic operations, integrating this lipid dye is critical when processing non-porous items recovered from difficult environments. Crime scene investigators frequently encounter wet evidence or food-contaminated packaging where standard reagents cannot adhere. Because Sudan Black selectively stains the water-insoluble fats, the formula is highly effective at rescuing difficult prints. Extracting usable intelligence requires a chemical approach designed specifically for challenging grease-based residues.\u003c\/p\u003e\n\u003cp\u003eWhen processing evidence, the working solution is typically applied via complete submersion in a shallow tray or controlled pouring. Technicians monitor the surface as the dark coloration develops over the latent friction ridges, usually requiring several minutes for full saturation. Once the desired contrast is achieved, the evidence is immediately rinsed with cool tap water to clear the background before final photographic documentation.\u003c\/p\u003e\n\u003ch2\u003eForensic Reagent Comparison: Why Choose Rocky Mountain Reagents?\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eRocky Mountain Reagents Sudan Black\u003c\/th\u003e\n\u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eTypical Competitor\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFormat\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePre-mixed liquid\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eRequires manual powder mixing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eConsistency\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eStandardized working strength\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVariable batch quality\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBelow retail pricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFull retail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eShips From\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eUSA inventory\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVaries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eAcademic and Institutional Pricing\u003c\/h2\u003e\n\u003cp\u003eLabSupplies.com offers tiered quantity pricing for academic and research institutions.

It is also exceptionally useful for processing non-porous evidence that has been recently submerged in water.\u003c\/p\u003e\n\u003ch3\u003eWhy use this instead of Cyanoacrylate (Superglue) fuming?\u003c\/h3\u003e\n\u003cp\u003eSuperglue fuming requires moisture to polymerize the fingerprint, but heavy grease or excessive standing water can inhibit this reaction, rendering cyanoacrylate ineffective. Sudan Black bypasses this issue entirely by chemically binding directly to the insoluble lipids (fats) left behind in the sweat residue, regardless of water exposure.\u003c\/p\u003e\n\u003ch3\u003eDoes this product need a special clearing buffer?\u003c\/h3\u003e\n\u003cp\u003eNo, unlike some other lipid stains (like Oil Red O), Sudan Black generally does not require a complex chemical clearing buffer. Once the deep blue-black prints have sufficiently developed on the surface, technicians simply rinse the evidence under cool, gently flowing tap water to clear the background dye.\u003c\/p\u003e\n","brand":"Rocky Mountain Reagents","offers":[{"title":"500 mL","offer_id":48416750665960,"sku":"'PF-SB-500mL","price":62.0,"currency_code":"USD","in_stock":true},{"title":"1 L","offer_id":48416750698728,"sku":"'PF-SB-1L","price":93.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/5361\/1240\/files\/PFLOGO_jpeg_1bc58415-38ff-415e-a908-049cda8410e3.webp?v=1777428983","url":"https:\/\/labsupplies.com\/products\/sudan-black-reagent","provider":"LabSupplies.com","version":"1.0","type":"link"}
