Heathrow Scientific® PCR Cooler

 

Ice-free cooling system for PCR preparation and sample storage.

 

Keep your PCR samples at optimal temperatures without the hassle of ice. This Ice-Free PCR Cooling System is a modern, compact solution designed to maintain cold, stable conditions during sample prep and short-term storage. Ideal for molecular biology, clinical diagnostics, and high-throughput laboratories, this cooler offers reliable, consistent cold storage for 96-well PCR plates without the mess and variability of ice buckets.

 

Engineered for performance and convenience, the unit cools rapidly in freezers and retains a temperature of 0°C for over an hour on the benchtop. Even with the lid off, it maintains sample temperatures below 5°C for up to 3 hours, helping to preserve sensitive reagents and DNA/RNA samples.

 

A built-in temperature indicator alerts you when the internal temperature rises above 6°C via a clear, contrasting color change, so you’ll always know when to re-chill. The patented lid design securely covers samples during freezer storage and easily converts into a stand, elevating the cooler for ergonomic access during pipetting or PCR prep.

 

Made from durable, sealed, and sonic-welded materials, this cooler keeps the coolant safely contained, offering leak-free, worry-free operation. Designed for both right- and left-handed users, the ambidextrous lid detaches and reattaches as needed for flexible use. The alphanumeric well markings ensure fast, easy identification of sample tubes, while a vented lid enables faster chilling of the entire unit.

 

Key Features

  • Ice-free cooling for 96-well PCR plates
  • Maintains 0°C for 1+ hour, and <5°C for up to 3 hours (with lid off)
  • Temp. indicator signals when samples exceed 6°C
  • Innovative lid doubles as a stand for hands-free access
  • Freezer-to-bench design for convenient transport and setup
  • Anti-freeze well design prevents freezing of samples
  • Sealed, sonic-welded body so no coolant leaks or spills
  • Stackable, space-saving footprint for crowded lab benches
  • Ergonomic textured grips ensure safe handling with gloves
  • Ambidextrous lid design for both left- and right-handed users
  • Alphanumeric well ID for fast sample location
  • Vented lid allows for rapid chilling in the freezer
