A convenient alternative to water-based ice packs and gel packs

PureTemp comes in foam bricks, hard bottles and a 2-cell pillow panel. Constant temperature during freezing or melting provides constant temperature control. Less PureTemp material is required for temperature control when compared to water-based refrigerants.

The durable 2-cell pillow panel design of F20202A allows for a protective wrap around highly temperature sensitive specimen samples and diagnostic materials during transport and shipping that cannot experience a deviation of temperature less than 4 °C. Use this advanced phase change technology in combination with an insulated shipper or envelope for additional assurance. Ideal for the prevention of cold shock when it matters most. The PureTemp product remains in a liquid state when the surrounding temperature is greater than 4 °C. When exposed to temperatures less than 4°C, the phase change material will begin to solidify and release stored energy thereby protecting the product from cooler temperatures.

When the surrounding temperature of the PCMs falls below the phase temperature, they solidify and release their stored energy. If the temperature rises above the phase temperature, they liquefy and absorb excess energy. These two phenomena protect the product from excessive heat and cold to help maintain product temperature for extended periods of time. PureTemp is engineered to react to a precise temperature, from -40 ° to +37 °C, and to operate in a very narrow temperature range. It is also renewable and biodegradable.
