What temperature range is considered suitable for a warmer?

The suitable temperature range for a warmer is indeed between 30 to 40 degrees Celsius. This range is ideal for maintaining the efficacy of certain medications and biological products that require a warm environment to remain stable. Conditions above room temperature help prevent microbial contamination and degradation, which can occur at lower temperatures.

In contrast, other temperature ranges listed in the options are not suitable for a warmer. The range of 2 to 8 degrees Celsius is typically used for refrigeration, which is appropriate for keeping medications cool, while -25 to -10 degrees Celsius is relevant for freezing or cryogenic storage, where certain products are kept at much lower temperatures to preserve their integrity. The Fahrenheit range of 59 to 86 degrees involves ambient conditions that, while warm, can vary outside the controlled environment necessary for specific pharmaceutical needs.
