CoolRack M15, gray, holds 15 x 1.5 or 2ml microfug CS1

Corning CoolRack thermo-conductive microfuge tube modules eliminate variability which originates from tubes placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources. Place the CoolRack module directly onto a temperature source between -196C to >100C and it will rapidly adapt to that temperature.
