Nine liters of dry ice sublimating into an open tray disappears faster than most researchers expect — and once it is gone, every sample in the tray is at risk. The Globe Scientific 455025 Series addresses this directly with a fitted polyurethane foam lid sized to seal the full 20.5" × 14.875" cavity, creating an insulated chamber that dramatically extends the working life of both dry ice and wet ice. In high-volume labs where the tray may sit loaded for two or three hours during tissue processing, biobank accessioning, or multi-student practicals, the lid is the difference between one ice fill and two. The tray body and lid share the same closed-cell polyurethane foam construction — fully compatible with liquid nitrogen, dry ice, wet ice, and corrosive salt solutions. Molded handles on the tray base keep the loaded unit stable during transport, and four color choices support station or team assignments in shared facilities.
Features and Benefits
Full-Coverage Lid: Oversized polyurethane foam lid seals the entire 9-liter cavity, cutting heat exchange and extending dry ice and wet ice duration through long processing sessions.
9-Liter Capacity: The largest ice tray in the Globe Scientific range — holds multiple racks, high tube counts, and bulk containers for demanding workflows.
Closed-Cell Polyurethane Foam: Both tray and lid are made from insulating foam that resists thermal shock and outperforms rigid plastic on heat retention.
Cryogenic Safe: Tray and lid both handle liquid nitrogen, dry ice, wet ice, and salt solutions without cracking, warping, or material degradation.
Chemical Resistant: Withstands solvents, dilute acids, bases, and saline solutions without surface breakdown — important in high-use communal settings.
Heavy-Duty Molded Handles: Dual grips on the tray body support confident two-handed transport at full load, which can exceed 20 lbs with ice.
Color Coded: Blue, Green, Black, and Red options enable station, team, or department-level identification in multi-user labs and teaching facilities.

Laboratory Applications
Biobank and biorepository accessioning — lid preserves dry ice through the full intake workflow while dozens of vials are logged and sorted
Multi-hour tissue processing and histology grossing — sealed chamber keeps specimens at stable cold temperatures throughout extended sessions
Teaching lab practicals — provides a shared covered ice station that lasts the full class period without TA intervention to refill ice
Inter-building or inter-floor specimen transport — lid prevents spillage and minimizes cold loss during transit, acting as a sealed transport container
Overnight enzyme or antibody incubation setups — sealed 9L volume holds enough ice mass to maintain cold temperatures for extended periods in cold rooms
Frequently Asked Questions
How long will dry ice last in the sealed 9-liter tray?
Duration depends on ambient temperature, how often the lid is removed, and the initial mass of dry ice. The sealed polyurethane chamber substantially slows sublimation compared to an open tray. Users in climate-controlled labs typically report multiple hours of usable dry ice from a single fill — significantly longer than the open 455024 Series under the same conditions.
Is this tray suitable for shipping biological samples?
The 455025 is designed as a benchtop and transport tray within a facility, not as a certified shipping container. For shipping, use validated insulated shippers with gel packs or dry ice per your institution's SOP. The 455025 works well for staging samples before they are transferred into a shipper.
Does the lid lock or latch onto the tray?
No — the lid is a friction-fit design that seats on top of the tray rim. It stays in place during stationary use and gentle transport but is not latched. This allows quick access during active bench work without fumbling with clips or clasps.
Can I stack a second tray on top of this one?
The foam lid is not designed to bear the weight of a loaded tray stacked on top. If you need vertical space efficiency, consider placing multiple trays side by side on a lab cart or shelf rather than stacking.
Which size is best for a teaching lab — 4L or 9L?
For a shared station serving 3–6 students, the 9L (455025) provides enough capacity to last a full class period. The 4L (455023) works better for individual or paired workstations where bench space is limited. Both are available with lids and in four colors for group assignments.
