Heathrow Scientific True North™ Mini Benchtop Coolers keep 0.5–2.0 mL tubes cold during bench workflows where temperature drift can degrade enzymes, PCR reagents, and other temperature-sensitive samples. Use them on the benchtop or stage them in a freezer to deliver predictable cold contact without ice baths.
Choose 0°C models for routine reagent setup and short bench handling, or -20°C models for colder staging. For longer hold times, select the gel-filled lid versions (see the model table below for verified retention times).

Controlled bench cooling without condensation and pooling water from ice trays.
Frequently Asked Questions
What tube sizes fit these mini coolers?
These models are specified for 0.5 to 2.0 mL tubes (32-well, 4 × 8 array). 0.5 mL tube adapters are supplied for the 0.5–2.0 mL versions.
What is the difference between clear-lid and gel-filled lid models?
Gel-filled lid models are designed for longer temperature retention than clear-lid models. See the “Available Models” table for the verified retention times for each SKU.
How should I pre-chill the cooler before use?
Pre-chill the unit in the appropriate freezer (0°C or -20°C model selection) and use the included temperature-retention graph to match hold time to your workflow.
Is there a warranty?
Yes. The manufacturer specifies a 2-year warranty for these mini benchtop coolers.
Quality Assurance
These mini coolers are specified with a polycarbonate body, gridded/keyed lids for identification, and include a temperature-retention graph for quick validation. Manufacturer documentation lists a 2-year warranty.
