Reotemp’s ReoCube™ Isolation Bottles are used to monitor the temperature of ultra low freezers or refrigerators. The isolation bottles are filled with fluid (typically ethylene glycol, alcohol, or a cryopreservative). Then, up to three temperature sensors are inserted into the bottles and liquid. By submerging the temperature sensor(s), the ReoCube ensures the temperature readings will not be thrown off when the freezer door is opened and ambient air rushes in. The result is a highly stable and reliable temperature reading that mimics the temperature of the critical medium being cooled.
