Heathrow Scientific 120727 PCR Cooler 96-Well Pink/Purple is a polypropylene and polycarbonate ice-free cooling system designed for PCR preparation and storage.
Heathrow Scientific 120727 PCR Cooler is a 96-well, ice-free cooling system for thermosensitive PCR® preparation, cell-based assays, and sample storage — sold in a pack of 2. Made from polypropylene with a polycarbonate lid, each cooler maintains the entire 96-well plate at 0°C for over an hour and keeps sample temperatures below 5°C for up to three hours with the lid off. When the temperature ceiling of 6°C is exceeded, the cooler signals the user with a contrasting color change from purple to pink — a visible, no-thermometer alert that protects reaction integrity at a glance.
Features & Benefits
- Color-Change Temperature Alert: Transitions from purple to pink when the 6°C ceiling is exceeded — no thermometer needed. Immediate visual confirmation that samples are still within safe temperature range.
- Maintains 0°C for Over 1 Hour: After 2 hours pre-cooling at -20°C, the entire 96-well plate is held at 0°C for over an hour — keeping thermosensitive reagents, enzymes, and reactions protected throughout setup.
- Below 5°C for Up to 3 Hours: With the lid off, sample temperature stays below 5°C for up to three hours — providing an extended working window for high-throughput plate setup.
- Patented Lid Doubles as a Stand: The polycarbonate lid slides out, rotates 180°, and becomes a stand — elevating the cooler off the benchtop to minimize conductive heat transfer and extend cold-holding time.
- Universal 96-Well Compatibility: Fits industry-standard 0.2 mL and 0.5 mL PCR® tubes, strips, single-format tubes, and most 96-well assay plates in both standard and low-profile well shapes.
- Alphanumeric Well IDs: Each well is labeled with alphanumeric coordinates for fast, error-free sample location and retrieval during high-throughput runs.
- Ergonomic Textured Grip: Finger grips on both sides provide a secure, non-slip hold — especially important when transporting samples between freezer, bench, and thermocycler while wearing gloves.
- 2-Year Warranty: Backed by Heathrow Scientific's standard 2-year warranty on the cooler body.

Laboratory Applications
The 120727 PCR Cooler is purpose-built for any workflow where thermosensitive reagents must be kept cold during bench setup. Molecular biology labs use it to protect master mixes, polymerases, and restriction enzymes during 96-well plate assembly. Genomics and NGS prep labs rely on the ice-free format to avoid condensation and sample dilution from melting ice. Cell biology labs use it for gentle sample thawing and stopping of reactions. The color-change alert makes it particularly valuable in busy labs where multiple researchers share bench space — anyone can see at a glance whether the cooler is still within temperature range, without interrupting their workflow to check a thermometer.
Frequently Asked Questions
How long does the Heathrow Scientific 120727 PCR Cooler maintain 0°C?
After pre-cooling for 2 hours at -20°C, the 120727 maintains the entire 96-well plate at 0°C for over one hour. With the lid off, sample temperatures stay below 5°C for up to three hours. Pre-cooling time at -80°C may extend performance further.
What does the color change on the PCR Cooler indicate?
The 120727 transitions from purple to pink when the cooler's temperature exceeds the 6°C ceiling. This is a built-in visual alert that samples may be warming beyond safe range — no thermometer required. Once the cooler warms beyond this point, it should be returned to the freezer for re-cooling before continuing.
What tube formats are compatible with the 120727 PCR Cooler?
The cooler accepts 0.2 mL and 0.5 mL PCR® tubes, 8-strip tubes, single-format tubes, and most standard and low-profile 96-well assay plates. For compatible 96-well PCR plates and strips, see the Globe Scientific 96-Well PCR plates available in the LabSupplies catalog.
How does the lid work as a stand?
The polycarbonate lid slides out from the cooler body, rotates 180°, and locks back in to form a stand that elevates the cooler above the benchtop. This eliminates direct conductive contact with the bench surface, slowing heat transfer and extending the cooler's working time. The lid is ambidextrous and can be configured for left- or right-hand orientation.
