Abstract
A positioning device for a temperature sensor in a flask for freeze drying. The device comprises a generally circular plastic stopper having an opening approximately in its center. The stopper is snap-fittingly secured to the top of the flask. A central, annular tube extends through that opening and into the flask. A thermocouple having a generally circular cross section is coiled around and supported by the annular tube so that it is free and is in the center of the flask. The thermocouple is retractable and extensible to permit the use of the thermocouple in flasks of various lengths.
