Hi Everyone, this is my first post on this site! I am seeking advice to help me construct a home-made melting point apparatus (M.P.A). A melting point apparatus allows it's operator to determine the melting point of a chemical sample by heating it in a controlled fashion and noting the temperature when the sample melts. I have most of the design made up in my head, but I'm not sure as to how I can obtain the proper heating element. The heating element I am seeking is an emulation of the M.P.A.s heating elements in my school's chemistry lab, which look like this: a metal block (about 3cm tall by 2cm deep by 3 cm wide) with vertical holes bored into the face with a pane of glass pressed against said holes so a glass capillary tube (containing the sample) can be slid into the bored hole and viewed through the glass pane as the sample is heated by the metal. Another hole is bored into the metal, adjacent to the sample hole, for a thermometer. So again, my question is do you have any suggestions as to where I could by a heating element like this? Or, any suggestions on how to build one? I have a jewelry shop at my disposal so I can probably bore any holes myself. Any suggestions will be appreciated, thanks!
