Protect, organize, and transport standard 3" x 1" (75 mm x 25 mm) microscope slides with Marketlab Polycarb Slide Boxes. Constructed from high-impact polycarbonate, these heavy-duty storage boxes are built to withstand ultra-low temperature cryogenic environments down to -80°C as well as standard autoclave cycles. Each box features uniform, grooved channel slots with a temperature-resistant lined base to cushion delicate glass and prevent slide-to-slide contact. Complete with a friction-fit lid, rust-resistant stainless-steel clasp, and an indexed inventory card inside the cover, they offer maximum protection and easy sample identification for histology, pathology, and clinical research laboratories.
