The PPC construction provides superior low-temperature structural integrity compared to standard PP, keeping the friction-fit snap-close lid intact after repeated −20°C storage cycles — a critical advantage for immunofluorescence frozen sections and cold-chain cytology programs. Supplied non-sterile in 50\/Bag, part number 240-3071-080 is the cold-storage-capable upgrade from the standard PP variant in this product line.\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\u003e240-3071-080\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 (standard format)\u003c\/td\u003e\n\u003ctd\u003e25 × 75 × 1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene Copolymer (PPC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural (semi-translucent)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClosure\u003c\/td\u003e\n\u003ctd\u003eFriction-fit snap-close lid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCold Storage Suitability\u003c\/td\u003e\n\u003ctd\u003e−20°C and below\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;

The semi-translucent natural finish allows visual confirmation of slide presence and orientation without opening the mailer, reducing handling errors in high-volume pathology and consultation workflows. LabSupplies.com is an authorized dealer and ships from USA inventory; tiered pricing is available for hospital systems, reference laboratories, and research institutions with recurring volume requirements. The standard PP variant (240-3071-030), a two-slide PP mailer (240-3072-030), and a multi-slide PP mailer (240-3074-030) are also available for applications that do not require cold-chain storage compatibility.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhy choose the PPC mailer over the standard PP version?\u003c\/strong\u003e\u003cbr\u003eThe PPC construction in these mailers maintains structural integrity and a secure snap-close lid at −20°C and below, whereas standard PP can become brittle and prone to lid cracking at frozen temperatures.
