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

The embedded Datamatrix code at the bottom of each vial along with the corresponding "Code 128" barcode on the body of the vial, saves time and provides accurate organization and tracking of valuable samples.

The 2D vials can be safely stored in polycarbonate boxes (purchase separately). The storage boxes also feature the 2D Datamatrix code and Code 128 barcode to provide automatic identification of both the box and stored vials.

CoolCaddy™ PCR Work Station

• Maintains 2 to 4° C for up to 5 hours
• Keeps samples cool, but not frozen
• Accomodates several different vessel types: Vials, Tubes, Strips, Plates & Reservoirs

Protect your enzymes, reagents and temperature sensitive samples with the new 5-hour CoolCaddy™.  No need for messy ice baths - simply store it overnight in any standard freezer and its ready to hold tubes, plates and reservoirs at 2 to 4° C for an entire morning or afternoon.  CoolCaddy™ is an ideal work station for PCR and especially for any protocol requiring multi-channel pipetting from a reservoir into strip tubes or 96 well plates.  And, if your work is interrupted, just place the whole CoolCaddy™ (complete with samples and reagents) back in the freezer or refrigerator until you are able to resume your experiment.

The CoolCaddy™ offers the highest level of enzyme protection and is essential for all protocols that call for more than 30 minutes of benchtop prep work.  Additionally, the proprietary refrigerant gel protects enzymes, samples and reagents from freezer fluctuations caused by power outages, open doors, and frost-free cycles.

IsoFreeze® MCT Color-Change Racks

Leave the Ice Buckets Behind!
IsoFreeze Color-Changing Racks take the guesswork out of sample preparation!

Using proven IsoFreeze temperature maintenance technology, the filled racks maintain a cool (refrigerator) environment on the bench or the workstation platform. This helps maintain a stable environment for PCR reagents, cells, enzymes, or other temperature-sensitive reagents. Industry Standard format tubes, strips, and 96 well plates, in both standard and low profile well shapes, are accommodated and are efficiently cooled in PCR, QPCR, and many other applications.

IsoFreeze PCR Racks are manufactured using polypropylene containing temperature-dependent color-change dye giving at-a-glance temperature indication for each well. There is a dramatic change to a contrasting color at 7ºC. IsoFreeze gel technology means the wells will stay cool for up to 4 hours, depending on ambient temperature and other factors.

• Available in 2 color changing formats
• Material: Rugged polypropylene and inert gel
• Maintains temperature of less than 4°C for up to 2.5 or 3.5 hours depending on Rack
