Polypropylene 0.2 ml chill rack changes color as the temperature increases. To use, simply pre-chill the rack at -20°C, move it to your bench, and add your tubes. The rack slowly warms to 4°C and remains there for over 3 hours. The color changes as the rack reaches +7°C. Use to prepare cycle sequencing reactions, restriction digestions, or prevent non-specific primer annealing in 0.2 ml tubes or 96-well PCR plates. Measures 5.56" L x 3.9" W x 1.74" H with the locking lid.

Choose green/yellow or purple/pink.
