Globe Scientific 1L Ice Tray with Lid - 455021 Series | Sealed Polyurethane Insulation

Every minute your ice tray sits open on the bench, evaporation steals cold capacity and condensation drips onto your workspace. The Globe Scientific 455021 Series solves this with a fitted polyurethane foam lid that locks in temperature and blocks moisture exchange — extending effective chill time by limiting direct air contact with the ice surface. Built from the same closed-cell polyurethane foam as the open-top 455020 Series, this 1-liter lidded tray handles liquid nitrogen, dry ice, wet ice, and corrosive salt solutions without cracking or degrading. The lid seats securely on the tray body and lifts off cleanly for quick sample access, while molded handles on the tray base keep transport stable even when fully loaded. Choose from four colors to match your lab's organizational system.

Features and Benefits

• Included Lid: Fitted polyurethane foam lid limits evaporation and reduces condensation, extending ice life and keeping the benchtop dry.

• Material: Closed-cell polyurethane foam provides superior insulation and resists thermal shock from cryogenic substances.

• Cryogenic Compatible: Rated for use with liquid nitrogen, dry ice, wet ice, and salt solutions without material breakdown.

• Chemical Resistance: Withstands contact with laboratory solvents, dilute acids, and saline solutions without deterioration.

• Compact 1-Liter Capacity: Dimensions of 9.125" × 8.5" × 5.5" fit neatly on the benchtop beside instruments and pipetting stations.

• Molded Handles: Built-in grip handles on the tray body allow safe, stable carrying even when loaded with ice and samples.

• Color Coded: Available in Blue, Green, Black, and Red to distinguish experiments, users, or departments at a glance.

Specifications

Laboratory Applications

• Extended benchtop chilling of enzymes, antibodies, and heat-labile reagents where evaporation control matters

• Covered dry ice storage for sample transport between buildings or floors without rapid sublimation loss

• Maintaining cold chain integrity during multi-step pipetting protocols in molecular biology and clinical labs

• Reducing condensation and melt-water on shared benchtops in high-humidity lab environments

Frequently Asked Questions

How much longer does ice last with the lid on compared to the open tray?

The polyurethane lid significantly reduces sublimation of dry ice and melting rate of wet ice by limiting air exchange. While exact times depend on ambient conditions, users typically report noticeably extended chill duration compared to the open 455020 Series, especially when using dry ice.

Is the lid permanently attached or removable?

The lid is fully removable. It seats on top of the tray body for a snug fit but lifts off cleanly for fast sample access. There are no hinges or latches to break.

Can I use this tray with liquid nitrogen?

Yes. Both the tray and lid are manufactured from polyurethane foam that is fully compatible with liquid nitrogen, dry ice, wet ice, and salt solutions. The material will not crack or become brittle from cryogenic contact.

What is the difference between the 455020 and 455021 Series?

Both are identical 1-liter polyurethane foam trays. The only difference is the lid: the 455020 Series is the open-top version, and the 455021 Series includes a matching polyurethane foam lid.
