Globe Scientific PCR Cold Work Racks, SBS/ISBER Footprint, 96-Well, Color-Change 4°C Indicator — 1 Rack/Pack
The Globe Scientific PCR Cold Work Rack keeps reactions chilled at the bench without ice, holding samples near 4°C during PCR setup, plate loading, and enzymatic prep. Its SBS/ISBER footprint fits standard 96-well PCR plates and strip tubes, while a built-in color-change indicator signals when the rack is cold and ready to use.

Frequently Asked Questions
How long does the rack stay cold?
After freezing the cooling core per the included instructions, the rack maintains samples near 4°C for hours at the bench, eliminating the need for melting ice during PCR setup.
What does the color change indicate?
The thermochromic housing changes color when chilled — Green to Yellow or Purple to Pink — giving a clear visual cue that the rack is at working temperature and ready for use.
Will it fit my PCR plates and strips?
Yes. The SBS/ISBER footprint accepts standard 96-well PCR plates and 0.2 mL strip tubes, matching common thermal cyclers and automation decks.
Is the rack reusable?
Yes. The rack is designed for repeated freeze-and-use cycles, providing consistent cooling performance across many runs without consumable ice.
