Globe Scientific PCR Cold Work Racks, 4°C Color-Indicating Bench Cooling Racks, 1/Each The Globe Scientific PCR Cold Work Rack keeps samples chilled at 4°C during reaction setup, h olding PCR strips, plates, and individual tubes while preventing premature enzyme activity. Ideal for qPCR master mix assembly, library preparation, and reverse transcription workflows where maintaining low temperatures protects sensitive reagents. Color-changing models signal when the rack has warmed and needs re-freezing, giving bench scientists a quick visual cue.

Each unit carries lot numbering to support traceability for CAP-, CLIA-, and ISO 15189-accredited laboratories. Frequently Asked Questions How long does the rack hold 4°C after freezing? Hold time depends on ambient conditions, but the internal cooling gel sustains a chilled bench environment for typical reaction-setup sessions. Color-change models indicate when re-freezing is needed. What is the difference between the Blue and the Green/Purple racks? The Blue PCR-COLDCOR is a Corbett-style format holding 64×0.1mL strips, 16×0.2mL tubes, and 4×0.5mL tubes. The Green and Purple racks are 96-well formats for standard PCR plates and strips. Do the color-changing racks reset? Yes. The Green-to-Yellow and Purple-to-Pink racks display the cool color when properly chilled and shift as they warm. Re-freezing restores the original cool-state color for reuse. How are these racks sold? Each SKU is sold individually (1/Each). Listed prices are per unit. Tiered institutional and grant pricing applies to larger quantities. { "@context": "https://schema.org", "@type": "Product", "name": "Globe Scientific PCR Cold Work Racks, 4°C", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "description": "4°C PCR cold work racks for strips, plates, and tubes with color-change indicators.
