So the melting point of adex is between 81-82 degrees C. being as water boils at 100C you'll be fine using this method.
You'll first need some capillary tubes and a decent immersion thermoter

This is where it gets a bit tricky. I would probably use a glass beaker to boil the water so you're able to see clearly when the sample begins to melt. be sure to calibrate thermo and account for any discrepancy in the range.

anyway, this is how I've done it in the past. if anyone else has a more reliable or easier method im all ears.

I think a hot plate and a thermo gun would work well too..
