The invention relates to a device for monitoring the temperature of a cryogenically preserved biological sample. The device (10) comprises a sample container (1) having a receptacle space (2) for accommodating a biological sample (6). The device further comprises at least one chamber (11), the interior (12) of which is not fluidically connected to the receptacle space, and which is at least partially filled with an indicator substance (7) having a boiling point or sublimation temperature in a range from −10° C. to −140° C. The chamber (11) further has at least one opening via which the indicator substance (7) can escape from the interior (12) of the chamber (11) upon exceeding its boiling point or sublimation point. The invention further relates to a method for monitoring the temperature of a cryogenically preserved biological sample.

Temperatures of cryo-electron microscopy samples are assessed based on images portions associated with high temperature superconductor (HTSC) areas or other thermal sensor materials that are thermally coupled to or thermally proximate the samples. Such thermal areas can be provided on sample mounts such as metallic grids, carbon films, or on sample stages. In examples using HTSCs, HTSCs having critical temperatures between −175° C. and −135° C. are typically used.

A temperature sensor, a temperature measuring device comprising the temperature sensor, and a temperature measuring method using the temperature sensor are disclosed. The temperature sensor is disposed at a measurement target having an extremely low temperature and transmits temperature measurement data to a temperature measurement output unit through a lead wire. The temperature sensor includes a housing, an electric resistor disposed in the housing, and a thermal anchor portion disposed inside or outside the housing and connected to the lead wire. Further, the lead wire extending from the thermal anchor portion is connected to the temperature measurement output unit.
