The natural (clear) polystyrene construction provides the optical clarity needed for visual sample inspection before aspiration, while the 25 mL capacity delivers adequate headspace for inversion mixing without spillage and accommodates the aspiration dead volume required by platforms running 60–120 samples per hour. Part number 201-5266-01S is a direct match to the open-top vial format specified by Beckman Coulter, Abbott, and other major hematology analyzer platforms.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003e201-5266-01S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity\u003c\/td\u003e\n\u003ctd\u003e25 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGeometry\u003c\/td\u003e\n\u003ctd\u003eCylindrical, Open Top\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolystyrene (PS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural (clear)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eNon-Sterile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Size\u003c\/td\u003e\n\u003ctd\u003e50\/Bag (Vials only — no caps included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPA \/ Phthalate \/ Latex\u003c\/td\u003e\n\u003ctd\u003eBPA-Free, Phthalate-Free, Latex-Free\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCBC\/DIFF pre-dilution: receives a precisely metered blood aliquot and isotonic diluent (typically 1:224 to 1:500 depending on the analyzer and panel) prior to automated aspiration\u003c\/li\u003e\n\u003cli\u003eHigh-throughput clinical hematology labs running 60–120 samples per hour where caps are dispensed or managed by the analyzer's dilution arm\u003c\/li\u003e\n\u003cli\u003eManual bench dilution and inversion-mixing protocols requiring a 25 mL cylindrical vial format\u003c\/li\u003e\n\u003cli\u003eCost-optimized procurement workflows where vials and caps are sourced independently or caps are reused within the dilution rack system\u003c\/li\u003e\n\u003cli\u003ePre-dilution sample preparation for impedance-based cell-counting platforms where PS minimizes background optical interference\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThese 25 mL open-top dilution vials are compatible with a broad range of automated hematology platforms.
