Used extensively as the Kastle-Meyer test, this multi-part chemical kit reacts catalytically with the heme molecule found in hemoglobin. The resulting immediate pink coloration allows forensic professionals to quickly identify suspected biological evidence. Investigators rely on this targeted field set to distinguish potential bloodstains from other visually similar reddish substances.\u003c\/p\u003e\n\u003cp\u003eEngineered for demanding field and laboratory workflows, the pre-measured set eliminates formulation guesswork to maximize testing efficiency. By integrating the required reagents into a complete system, examiners achieve court-admissible presumptive results in seconds. When incorporated into standard operating sequences, the chemical reaction offers high sensitivity with a low rate of false positives. This ready-to-use configuration significantly streamlines preliminary biological screening prior to DNA collection.\u003c\/p\u003e\n\u003cp\u003eTo prevent sample contamination, investigators must carefully perform the test on a secondary cotton swab rather than applying chemicals directly to the stain. Maintaining proper handling ensures the original evidence remains intact for subsequent genetic profiling. For optimal laboratory safety, preparation and storage of these reagents should occur in controlled environments away from excessive heat. Technicians must utilize appropriate personal protective equipment during chemical handling.\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\"\u003ePF30040-15mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e15 mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDropper Set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePF30040-3x500mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e3 x 500 mL\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBulk Lab Set\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\"\u003ePresumptive Blood Test Kit (Kastle-Meyer)\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\"\u003eHemoglobin in suspected bloodstains\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eReaction Color\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eRapid Pink\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eApplication Phase\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePreliminary crime scene screening\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\"\u003eMulti-part sequential application\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 presumptive test kit is critical when processing complex crime scenes. Crime scene investigators frequently encounter ambiguous stains on clothing, flooring, or weapons that require immediate preliminary identification. Because it selectively reacts with peroxidase-like activity in blood, the multi-step formula is highly valuable for rapid triage. Extracting usable intelligence requires a verified chemical approach to guide further laboratory analysis.\u003c\/p\u003e\n\u003cp\u003eWhen executing the Kastle-Meyer process, the working solution involves a strict three-step sequential application on a swabbed sample. Technicians apply ethanol to expose the hemoglobin, followed by the phenolphthalein reagent, and finally a hydrogen peroxide oxidizer. Upon introducing the peroxide, a rapid pink color change indicates a positive presumptive result for blood. This critical triage step ensures crime labs only dedicate resources to actual biological evidence.\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 Phenolphthalein Set\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\"\u003eComplete multi-part set\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eIndividual components sold separately\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 testing 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 helps investigators quickly determine if a suspicious reddish stain is likely biological in nature or simply a false positive like rust, paint, or food coloring.\u003c\/p\u003e\n\u003ch3\u003eHow does the Kastle-Meyer test work?\u003c\/h3\u003e\n\u003cp\u003eThe test involves a strict three-step chemical process applied to a swabbed sample of the stain. First, an alcohol solution is applied to expose the hemoglobin. Next, the phenolphthalein reagent is added. Finally, hydrogen peroxide is introduced. If blood is present, the hemoglobin catalytically breaks down the peroxide, rapidly turning the phenolphthalein a bright pink color.\u003c\/p\u003e\n\u003ch3\u003eDoes this presumptive test destroy DNA evidence?\u003c\/h3\u003e\n\u003cp\u003eNot if performed correctly. Forensic protocols require investigators to gently rub a moistened cotton swab against the suspicious stain, and then apply the chemicals exclusively to that secondary swab.
