A device to determine phase transitions by means of thermal analysis using a sample taken from molten metal comprises an expendable measuring probe with a solidification chamber into which the molten metal flows, whereby the solidification chamber contains a thermocouple with which the course of cooling is recorded over a specific time period. According to the invention, the side walls of the solidification chamber 3 comprise a metal casing 4 that completely surrounds the chamber and extends lengthwise of the measuring probe 1.

Why it's free to use
- Filed September 18, 1990 and granted February 3, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 18, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 18, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
