CoolRack® Thermo-Conductive Tube Modules

CoolRack® vial and tube modules maintain sample temperature through direct contact with water, ice, dry ice, liquid nitrogen, heating block, or other common laboratory temperature sources. Use for cooling, snap freezing, heating, or thawing samples.

Overview

  • To begin, place the CoolRack module directly onto a temperature source between -196° C to >100° C and it will rapidly equilibrate to the source temperature. CoolRack tube modules 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 CoolRack modules may be autoclaved, high-heat sterilized or decontaminated with alcohol or other lab detergents.

Key Features

CoolRack Tube Module on ice

On Ice

  • Adapts from ambient (25° C) to < 4° C in 60 to 90 seconds*
  • Samples and labels stay dry and organized
  • Hours of ice cooling without direct ice contact
  • Reproducible method
CoolRack Tube Modules on dry ice

On Dry Ice

  • Adapts from ambient (25° C) to - 78° C in approximately 5 to 7 minutes*
  • Eliminates ethanol from snap freezing
  • Samples are upright and organized as they freeze
  • Equal or better freezing rate as compared to direct immersion into dry ice or alcohol slurry
  • Reproducible method
CoolRack on LN2

In Liquid Nitrogen (LN2)

  • Adapts from ambient (25° C) to approximately - 150° C in approximately 12 to 14 minutes*
  • Vapor barrier protects from ambient air
  • Samples are upright and organized as they freeze
  • No direct contact between samples and LN2
  • Reproducible method

With Heat Sources

  • Use with water baths, hot plates, incubators, and other heat sources to keep samples warm

*Average cooling rate from room temperature

Problem: Samples in Ice

Problem: Samples in Ice

  • Non-uniform ice contact results in variable sample temperature
  • Disorganized samples, wet labels
  • Shifting, sinking tubes; contamination risk
  • Non-reproducible method

Solution: Samples in CoolRack Tube Module

Solution: Samples in CoolRack Module

  • All samples <4°C and uniform in temperature (+/- 0.1°C)
  • Samples organized, secure and dry
  • All tubes upright and indexed
  • Reproducible method

How It Works

Cooling
Warming

Cooling

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

Warming

  • CoolRack in water bath: heat is transferred from the water bath toward relatively cooler CoolRack until equilibrium is reached.

CoolRack Reproducibility

CoolRack Graph

  • 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 CoolRack CF45 thermo-conductive module. The module was placed onto a ThermalTray platform in a 37° C water bath and allowed to equilibrate. The CoolRack CF45 module was then removed and placed onto dry ice and equilibrated to -78° C (0 to 15 minutes) and then returned to the water bath to re-equilibrate to 37° C (15 to 30 minutes). This experiment was repeated five consecutive times and temperature profiles were recorded.
  • Conclusion: the CoolRack CF45 module showed identical cooling profiles and phase transition (orange circles) over five consecutive freeze-thaw cycles.
