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. 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 sterilised or decontaminated with bleach, alcohol or other disinfectants or lab detergents.

• 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 organised, secure and dry
• All tubes upright and indexed
• 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, vapour 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
