Thermoconductive Tube Rack for 15 Microcentrifuge Tubes (formerly CoolRack® M15)

Thermoconductive Tube Rack for 15 Microcentrifuge Tubes 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)

• Ideal for cooling, snap freezing, heating or thawing
• Helps keep samples organized and dry
• All tubes upright and indexed
• Reproducible method

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

Key Features:

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 & 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: Ease of Use:

• Thermoconductive Tube Rack on ice: heat from the relatively warmer Thermoconductive Tube Rack module is transferred to cooling source (wet or dry ice, cartridge, LN2) until equilibrium is reached
• Thermoconductive Tube Rack in water bath: heat is transferred from water bath toward relatively cooler Thermoconductive Tube Rack until equilibrium is reached
