Corning CoolRack thermo-conductive 384-well plate modules eliminate variability which originates from plates placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources. Place the CoolRack module directly onto a temperature source between -196°C to >100°C and it will rapidly adapt to that temperature. CoolRack modules ensure +/- 0.1°C temperature uniformity across all plates when cooling, snap freezing, heating or thawing. All CoolRack modules may be autoclaved, high heat sterilized or decontaminated with bleach, alcohol or other disinfectants or lab detergents. 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. SBS-compatible.
