Multi-step protocols do not pause while you refill your ice. The Globe Scientific 455023 Series pairs a 4-liter polyurethane foam tray with a matching insulated lid, creating a sealed cold chamber that dramatically slows ice melt and dry ice sublimation during long bench sessions. This matters most in batch workflows — protein purifications, ELISA plate loading, or multi-sample aliquoting — where your samples may sit on ice for an hour or more while you work through the full set. The lid seats flush against the tray rim to block warm air exchange, yet lifts off instantly when you need access. The same closed-cell polyurethane foam construction handles liquid nitrogen, dry ice, wet ice, and salt baths without material failure, while the 4-liter footprint accommodates a full tube rack or multiple reagent containers without overtaking the bench. Four colors let you match your lab's organizational scheme.
Features and Benefits
Fitted Polyurethane Lid: Matching foam lid seats flush on the tray to limit air exchange, significantly extending ice life and reducing dry ice sublimation during long protocols.
4-Liter Working Volume: Sized for batch work — accommodates a full tube rack, multiple 50 mL conicals, or several reagent bottles surrounded by ice.
Closed-Cell Polyurethane Foam: Superior insulation versus rigid plastic trays, with built-in resistance to thermal shock from cryogenic substances.
Full Cryogenic Compatibility: Tray and lid both rated for liquid nitrogen, dry ice, wet ice, and salt solutions without cracking or material failure.
Chemical Resistant: Foam body and lid withstand contact with solvents, dilute acids, bases, and saline commonly encountered during laboratory work.
Molded Handles: Built-in grips on each end of the tray base provide stable two-handed transport when fully loaded.
Color Coded: Four color options (Blue, Green, Black, Red) support lab organization by station, protocol, or user.

Laboratory Applications
Long-duration protein purification — lid keeps samples chilled through multi-hour column chromatography or affinity purification steps
ELISA and immunoassay plate loading — preserves reagent integrity across the full plate-loading workflow without ice refills
Covered transport of clinical specimens — lid prevents spillage and maintains cold chain while moving between collection and processing areas
Dry ice storage during tissue sectioning — lid slows sublimation, reducing the frequency of dry ice refills during cryostat work
Multi-user lab stations — assign color-coded lidded trays to individual researchers for accountability and contamination control
Frequently Asked Questions
Will a standard tube rack fit inside the 4-liter tray?
Yes. The internal dimensions (approximately 15" × 11.5") will accommodate most standard microcentrifuge tube racks and many conical tube racks when surrounded by crushed ice. Verify your specific rack dimensions against the tray specs before ordering.
How does the 4-liter compare to the 1-liter and 9-liter trays?
The 4L (455023 Series) is the batch-work tray — large enough for tube racks and multi-sample prep, compact enough to stay on the bench. The 1L (455021 Series) is a personal benchtop tray for a few tubes at a time. The 9L (455025 Series) is for high-volume or multi-user stations where maximum capacity matters most. All three share identical polyurethane foam construction and are available with or without lids.
Can I buy the lid separately if I already have the 455022 open tray?
Globe Scientific does not sell the lid as a separate accessory. If you need lid coverage, order the 455023 Series, which includes the tray and lid as a set.
Is the foam easy to clean after spills?
Yes. Wipe with mild detergent and water, then air dry. The closed-cell polyurethane foam resists liquid absorption, so spills stay on the surface rather than soaking in. Do not autoclave — polyurethane foam is not designed for steam sterilization.
