• Ice-free, stable cooling block for sample tubes
• Holds 40 x 1.5-2.0 mL tubes
• Maintains 4°C for up to 210 minutes
• Unique design reduces condensation
• Visual temperature indicator 

The Benchmark Scientific DC4020 DryChill ice-free cooling block holds forty 1.5 to 2.0 mL tubes and maintains a temperature of four degrees Celsius for up to 210 minutes.

The DryChill cooling blocks are designed to store samples safely on the lab-bench without sample degradation due to temperature increase or fluctuation. Unlike traditional ice buckets, these blocks do not require any ice and are uniquely designed to minimize condensation, resulting in convenient, mess-free cooling.

Each DryChill cooling block utilizes a proprietary gel refrigerant, designed to maintain cold (but not freezing) temperatures for extended time periods. Once the block temperature begins to warm, the visual indicator alerts the user by changing from purple to pink.
