Thermoconductive Tube Racks (formerly CoolRack®)

Thermoconductive Tube Racks: Supporting Sample Temperature Uniformity

Thermoconductive Tube Rack modules are precision-engineered sample modules manufactured from a novel thermo-conductive alloy material, designed to evenly distribute temperature across all wells providing uniform and consistent temperature to all samples (+/-0.1°C).

Thermoconductive Tube Rack modules eliminate variability which originates from tubes placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources. They ensure +/- 0.1°C temperature uniformity across all tubes when cooling, snap freezing, heating or thawing.

Suggested applications include cooling reagents such as restriction enzymes, dNTPs and antibodies, alcohol-free dry ice snap freezing of tissue, virus and bacteria samples and bench top cryogenic tube sorting in liquid nitrogen. All Thermoconductive Tube Rack modules may be autoclaved, high heat sterilized or decontaminated with bleach, alcohol or other disinfectants or lab detergents.

  • How It Works

    Thermoconductive racks are precision-engineered sample modules manufactured from a novel thermo-conductive alloy material. Thermo-conductivity is the transfer of heat energy from a higher temperature region to a lower temperature region. Thermoconductive racks evenly distribute the temperature across all wells providing very uniform and consistent temperature to all samples (+/0.1°C).

    How Thermoconductive Racks Work

     

    Cooling

    Cooling with thermoconductive rack

    Thermoconductive rack on ice: heat from the relatively warmer thermoconductive rack module is transferred to cooling source (wet or dry ice, cartridge, LN2) until equilibrium is reached.

    Warming

    Warming with Thermoconductive rack

    Thermoconductive rack in water bath: heat is transferred from water bath toward relatively cooler thermoconductive rack until equilibrium is reached.

  • Reproducible Method

    Performance test: a temperature probe was placed into a 2.0 mL cryogenic vial containing 1.0 ml of water. The tube was inserted into a thermoconductive rack CF45. The module was placed onto a Thermoconductive tray in a 37°C water bath and allowed to equilibrate. The thermoconductive rack CF45 module was then removed and placed onto dry ice and equilibrated to -78°C (0 - 15 minutes) and then returned to the water bath to re-equilibrate to 37°C (15 - 30 minutes). This experiment was repeated five consecutive times and temperature profiles were recorded.

    Conclusion: the thermoconductive rack CF45 module showed identical cooling profiles and phase transition (orange circles) over five consecutive freeze-thaw cycles.
