Heavy-Duty 100-Slide Storage & Mailing Boxes — PPC, Red, 4/Bag (258-6188-R30)
These heavy-duty 100-slide storage and mailing boxes are constructed from Polypropylene Copolymer (PPC) with a foam-lined base, providing significantly greater impact resistance than standard styrenic plastic slide boxes during courier sorting and postal handling. Designed for pathology consultation submissions, inter-laboratory slide transport, and archive programs, the 258-6188-R30 holds 100 standard 25 × 75 mm microscope slides in individual foam pockets that prevent slide-to-slide contact and protect irreplaceable tissue sections from breakage. Supplied in bags of four, these red boxes are suited for STAT and priority case identification in pathology routing and courier systems.

Applications
- Pathology consultation submissions and inter-laboratory slide transport requiring shell integrity through courier sorting and compression events
- Batch shipping of weekly accession sets and reference lab slide distribution programs
- Multi-case tumor board preparation where 100 slides from several cases must travel together as a single unit
- Cold-chain transport of immunofluorescence frozen sections and cryostat sections requiring −20°C stability through the shipping chain
- Long-term archive storage of FISH preparations, coverslipped IHC sections, and other fragile diagnostic slides where coverslip-edge chipping or reagent transfer between slides would compromise case integrity
- Priority and STAT case routing — the red shell provides instant high-visibility identification in pathology courier and internal sorting systems

Quality & Procurement
Made in USA (California), these Caplugs® Evergreen slide boxes are manufactured from BPA-free, phthalate-free Polypropylene Copolymer under ISO quality management processes. PPC resin is selected specifically for its impact toughness over standard polystyrene, making these boxes appropriate wherever shell cracking during courier handling would place irreplaceable diagnostic preparations at risk. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, with tiered pricing available for high-volume pathology labs, hospital systems, and reference laboratory networks.
Frequently Asked Questions
Why choose PPC over standard polystyrene slide boxes?
Polypropylene Copolymer absorbs drop and compression forces that commonly crack styrenic plastic shells during courier sorting. For irreplaceable tissue sections, consultation cases, or any slide set that cannot be re-cut, the heavy-duty PPC construction of these boxes eliminates the shell-breakage risk associated with standard plastic slide mailers.
What does the red color indicate, and are other colors available?
Red is conventionally used in pathology workflows to flag priority, STAT, or urgent consultation cases requiring expedited review, providing instant visual identification in courier and internal routing systems. A blue version (258-6188-B30) is also available for programs that use color to distinguish case priority levels or originating departments.
How does the foam-lined base protect slides during transport?
The foam base provides individual slide position friction retention without adhesive contact, so each slide seats securely in its own pocket and cannot shift or contact neighboring slides. This is especially important for fragile FISH preparations, coverslipped IHC sections, and immunofluorescence slides where even minor coverslip-edge chipping or reagent transfer between adjacent slides could compromise the diagnostic preparation.
Are these boxes suitable for frozen slide storage and cold-chain shipping?
Yes — PPC maintains its structural integrity and impact resistance at −20°C, making these boxes appropriate for cold-chain distribution of immunofluorescence frozen sections, cryostat sections, and other preparations that must be held at sub-zero temperatures from originating lab to receiving pathologist.
