CoolRack™ M30-PF 500ul Thermoconductive Tube Rack for 30 Microcentrifuge Tubes, 500ul

• 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

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

*Average cooling rate from room temperature

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