Abstract

See full text

A method and device (10) for positioning a probe (14), such as a temperature sensor, in a flask (12). A stopper adapted to be secured to an open end of the flask (12) is provided having an opening (32) through which a tube (34) extends. A clamping mechanism (40) is connected to the tube (34) to secure the probe (14) to the stopper. The clamping mechanism (40) comprises a first flange (44), and a second opposing flange (46) spaced slightly apart from the first flange (44). An O-ring (50) positioned around the flanges (44, 46) causes them to flex inward to engage and secure the probe (14) between them.
