Heavy-Duty 100-Slide Storage & Mailing Boxes — PPC, Blue, Foam-Lined Base (258-6188-B30)
These Caplugs® Evergreen heavy-duty slide storage and mailing boxes hold 100 standard 25 × 75 mm microscope slides in a foam-lined base that retains each slide individually by friction — no adhesive contact, no label abrasion, no coverslip disturbance during transport. The shell is molded from Polypropylene Copolymer (PPC), which delivers significantly greater impact resistance than standard styrenic plastic slide boxes, making these boxes the right choice for courier-transported pathology consultations, inter-laboratory slide distribution, and archive programs where shell breakage on irreplaceable tissue sections is an unacceptable risk. Supplied non-sterile in bags of 4, they are also rated for cold storage at −20°C, supporting frozen-section and cryostat-slide cold-chain programs.

Applications
- Pathology consultation submissions via courier or postal mail — heavy-duty PPC shell resists drop and compression forces in sorting environments
- Batch shipping of weekly accession sets and multi-case tumor board slide packages
- Reference laboratory and send-out slide distribution programs requiring reliable, reusable packaging
- Cold-chain transport of immunofluorescence frozen sections and cryostat slides maintained at −20°C through the shipping chain
- Long-term archive storage of H&E, IHC, FISH, and immunofluorescence preparations where slide-to-slide contact must be prevented
- Multi-color slide box systems — blue shell widely used to designate active consultation cases, current accession batches, or specific diagnostic categories

Quality & Procurement
Made in USA (California), these Caplugs® Evergreen slide boxes are produced under ISO 9001 quality management from BPA-free, phthalate-free Polypropylene Copolymer resin. PPC's toughened copolymer chemistry is the material basis for the heavy-duty impact rating — it is not a marketing designation but a measurable improvement over standard styrenic thermoplastic shells. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, with tiered pricing available for high-volume pathology departments, reference laboratories, and institutional purchasing programs.
Frequently Asked Questions
Why choose PPC over standard plastic slide boxes for mailing?
Polypropylene Copolymer absorbs the drop and compression forces common in courier sorting and postal handling far better than standard styrenic plastics, which can crack under the same conditions. For irreplaceable tissue sections or fragile FISH and immunofluorescence preparations, the PPC shell substantially reduces the risk of box failure during transit.
Will these boxes protect slides at freezer temperatures?
Yes. PPC maintains its impact resistance and structural integrity at −20°C, making these boxes suitable for cold-chain transport and frozen slide storage programs, including immunofluorescence frozen sections and cryostat preparations that must remain at sub-zero temperatures through the shipping chain.
Does the foam liner contact the slide labels or coverslips directly?
The foam base retains each slide by friction in individual position pockets. There is no adhesive contact, so slides release cleanly at the destination without label abrasion, coverslip edge disturbance, or mounting medium transfer between slides.
Are other colors or capacities available?
The same heavy-duty 100-slide format is available in Red (258-6188-R30). For single-case consultation submissions requiring fewer slides, the 25-slide format (258-6025 family) is also available from LabSupplies.com.
