CoolRack Thermoconductive Tube Rack modules eliminate variability which originates from tubes placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources. CoolRack Thermoconductive Tube Rack 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 Thermoconductive Tube Rack modules may be autoclaved, high heat sterilized or decontaminated with bleach, alcohol or other disinfectants or lab detergents.

Secure Sample Preparation
- Removes all problems created by placing sample directly in ice: variable sample temperature, wet labels, contamination risk
- All samples <4°C and uniform in temperature (+/- 0.1°C)
- Samples organized, secure and dry
- All tubes upright and indexed
Versatility and Performance
Regardless of temperatures source
- Samples stand upright and organized
- Reproducible method
On ice
- Adapts from ambient (25˚C) to <4˚C in 60-90 seconds*
- Samples and labels stay dry
Hours of ice cooling without direct ice contact
On dry ice
- Adapts from ambient (25˚C) to -78˚C in approximately 5-7 minutes*
- Eliminates ethanol from snap freezing
- Equal or better freezing rate as compared to direct immersion into dry ice or alcohol slurry
In liquid nitrogen
- Adapts from ambient (25˚C) to approximately -150˚C in approximately 12-14 minutes*
- Vapor barrier protects from ambient air
- No direct contact between samples and LN2
Heat sources
- Use with water baths, hot plates, incubators and other heat sources to keep samples warm
How it Works: Easy to Use
- 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
- CoolRack M6 in water bath: heat is transferred from water bath toward relatively cooler CoolRack until equilibrium is reached
