Heathrow Scientific 120729 PCR Cooler 96-Well is a Polypropylene and Polycarbonate benchtop cooler designed for maintaining PCR samples at 0°C for over an hour.
Heathrow Scientific 120729 PCR Cooler is a 96-well, ice-free cooling system sold as a mixed-color pack of 2 — one Pink/Purple cooler (120727 color) and one Lt.Blue/Dk.Blue cooler (120728 color). 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. Each unit signals the user with a distinct color change when the 6°C ceiling is exceeded — purple to pink or dark blue to light blue — making this mixed pack ideal for labs that need to visually separate projects, users, or reagent classes at shared benchtops from day one.
Features & Benefits
- One of Each Color: Pack includes one Pink/Purple and one Lt.Blue/Dk.Blue cooler — the most versatile starting configuration for labs that need visual sample separation across two concurrent workflows.
- Color-Change Temperature Alert: Each cooler transitions to a lighter shade when the 6°C ceiling is exceeded — no thermometer needed. Pink/Purple shifts purple→pink; Lt.Blue/Dk.Blue shifts dark→light blue.
- 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 0.2 mL and 0.5 mL PCR® tubes, strips, single-format tubes, and most standard and low-profile 96-well assay plates.
- Alphanumeric Well IDs: Each well is labeled for fast, error-free sample location and retrieval during high-throughput runs.
- 2-Year Warranty: Backed by Heathrow Scientific's standard 2-year warranty on both cooler bodies.

Laboratory Applications
The mixed-color 120729 pack is the default choice for shared lab benchtops, multi-user PCR setups, and core facilities where two researchers need to work simultaneously from separate coolers without cross-contaminating samples. One cooler can hold a master mix while the other holds template DNA, with the distinct colors preventing mix-ups during high-throughput plate loading. Genomics, NGS prep, qPCR, and cell-based assay labs all benefit from the visual color-separation that two differently-colored coolers provide. For labs that want two coolers of the same color, see the 120727 (Pink/Purple, pk2) or 120728 (Lt.Blue/Dk.Blue, pk2).
Frequently Asked Questions
What exactly comes in the 120729 PCR Cooler pack?
SKU 120729 contains two coolers: one Pink/Purple (identical to 120727) and one Lt.Blue/Dk.Blue (identical to 120728). Both are the same 96-well format, dimensions, and temperature performance — only the color and color-change indication differ. If you need two coolers of the same color, order 120727 (2× Pink/Purple) or 120728 (2× Lt.Blue/Dk.Blue).
How long does the 120729 PCR Cooler maintain 0°C?
After pre-cooling for 2 hours at -20°C, each cooler 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.
What does the color change indicate and how does it work?
Each cooler uses a thermochromic material that changes shade when the temperature exceeds 6°C — the Pink/Purple unit shifts from purple to pink, and the Lt.Blue/Dk.Blue unit shifts from dark blue to light blue. The change can occur across the entire cooler body or in individual wells, allowing users to pinpoint exactly which samples may have warmed.
What tube formats are compatible with the 120729 PCR Cooler?
Both coolers in the pack accept 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.
