Color Change Freezer Racks

These Color Change Freezer Racks provide a clear visual indicator of temperature, making them ideal for use and transport of samples. These reusable polypropylene racks have an operating range from -86°C to +121°C and can maintain a temperature below 4°C for nearly 3.5 hours at room temperature (with the lid on). The racks dramatically shift from green to yellow when the temperature rises above 7°C, offering an easy-to-see signal. They also feature an alphanumeric grid for organizing samples. Available in a 24-place option (6 x 4 array) for 1.5 mL to 2 mL micro tubes and an adapter for six 0.5 mL tubes, or a 96-place option (12 x 8 array) for 0.2 mL PCR tubes or strips. The racks are autoclavable and ideal for sample transport.
