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.
