How do you perform a melting point test?

Tough Old Man · 08-22-2005, 08:26 PM

I need to test my powder to determine whether it's prop or cyp. I know that prop melts between 197.6 and 204.8 degrees F. Cyp between 208.4 and 215.6 degrees. But how do you do it.

You take it to that point and see if it melts. Obviously you only have a few degrees of error to work with.

Well Water boils at 212 so, if you are limited on equipment, you could put a tempered beaker filled with water over flame and heat it to 197 degrees. You then take your powder in a seperate tempered vial and dip it into the heated water. Gradually heat the water and moniter the temp.

Keep in mind this will happen pretty quickly so you need to be paying very close attention.

Cool but how much powder. Are we talking about about a pinch, a 1/2 gram a gram? Help

Quanity doesn't matter, getting within a couple degrees though - is going to be fun with kitchen equipment. I would bring the temperature up very slowly watching a digital thermo, try to calibrate it to see where its at approximately for accuracy.

And again, talk to your source.

If you had access to a hot plate of some sort, it's much easier to control temp with them.

Ok I perform a melting point test and it melted at approx 210-218 degrees tell ing me it is cyp and not Prop. Prop melts at 244-251 degrees and the oven never reach more then 220 degrees. My source is going to send me another 50 grams. Thank you all for your help.

Now it time to take Dg's knowledge and put it to work. I have 20 grams left and hope I don't fuck this up like the other 30 grams. Shouldn't have any problems as i'll add bb to it this time.
