'Core' Correlated Temperature Indicators:

Biosynergy, Inc.'s 'Core' Correlated Temperature Indicators are affected by the same variables which affect your time/temperature sensitive samples.  The color visible on the indicators is dependent on the product temperature, the time at that temperature, the size or mass of the sample, and the heat transfer characteristics of the sample container.  The color dependence of these indicators on these variables assures you that the indicators will accurately monitor the temperature history of your precious materials.
