The friction-fit snap-close lid creates a secure mechanical closure that resists accidental opening under typical package-handling stresses, while the PP shell absorbs impact forces that would crack a bare glass slide in a standard envelope or bubble-wrap shipment. Supplied non-sterile in convenient 50\/Bag format, these mailers are well-suited to histopathology consultation submissions, cytology referrals, and inter-laboratory IHC or immunofluorescence slide sharing.\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\u003e240-3071-030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eOne-Slide Mailer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlide Capacity\u003c\/td\u003e\n\u003ctd\u003e1 standard microscope slide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlide Dimensions Supported\u003c\/td\u003e\n\u003ctd\u003e25 × 75 × 1 mm (standard format)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene (PP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural (translucent)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClosure Type\u003c\/td\u003e\n\u003ctd\u003eFriction-fit snap-close lid\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPA \/ Phthalates\u003c\/td\u003e\n\u003ctd\u003eBPA-free; no phthalate plasticizers\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\u003e\n\u003cstrong\u003eHistopathology consultation submissions:\u003c\/strong\u003e Single-slide enclosures prevent cross-contact between H\u0026amp;E-stained sections and special-stain slides during inter-facility transport.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCytology and Pap smear transport:\u003c\/strong\u003e The friction-fit closure protects slide labels and coverslips through postal and courier handling for cervical cytology, sputum, and BAL specimens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence (IF):\u003c\/strong\u003e Ideal for frozen-section kidney, skin, and direct IF slides; polypropylene is inert to mounting media and coverslip adhesives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e Single-specimen packaging for tumor marker and biomarker-stained slides sent for inter-laboratory review or second-opinion consultation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResearch specimen sharing:\u003c\/strong\u003e Cost-effective single-use protection for FISH, ISH, and other special-technique slides shared across academic or multi-site study networks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForensic pathology chain-of-custody transport:\u003c\/strong\u003e The labeling-ready outer surface accepts permanent markers, adhesive labels, and barcode stickers to support documentation from originating lab through to the receiving pathologist.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eChemical Resistance\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eReagent \/ Condition\u003c\/th\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAqueous buffers \/ saline\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDilute acids and bases\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlcohols (ethanol, isopropanol)\u003c\/td\u003e\n\u003ctd\u003eGood — short-term incidental contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eXylene \/ clearing agents\u003c\/td\u003e\n\u003ctd\u003eGood — short-term incidental contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard mounting media and coverslip adhesives\u003c\/td\u003e\n\u003ctd\u003eGood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAcetone \/ chlorinated solvents\u003c\/td\u003e\n\u003ctd\u003eNot recommended for prolonged exposure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, these Caplugs® Evergreen slide mailers are molded from virgin, BPA-free, phthalate-free polypropylene under ISO 9001 quality management.
