Simport's ChillBlock™ Tube Racks are made of a thermo-conductive metal alloy to eliminate the inconsistencies that occur when inserting tubes directly into ice, dry ice, alcohol baths, water baths, and other common laboratory temperature sources. Place the ChillBlock™ rack directly onto a temperature source and it will rapidly adapt to that temperature from -150°C to >+100°C. Racks ensure +/- 0.1°C temperature uniformity of all tubes when cooling, freezing, or heating.
ChillBlock™ 15 and 50mL Centrifuge Tube Racks are available in two configurations, one with 9 wells for 15mL centrifuge tubes and one with 4 wells for 50mL tubes. An alphanumeric grid allows for indexing rows and columns for easy tube location.
