Point Apparatus |
| The simplest method of measuring a melting point is by use of an oil bath (1). A round bottomed flask is partly filled with a mineral oil and the capillary tube containing the sample is attached to a thermometer with a rubber band. The oil is carefully heated with a microburner. The heated block apparatus (2) can be found in many shapes and sizes but the principle is the same; the sample is heated placed in an electrically heated block and the observations are made through a magnified port. The 'hot-stage' apparatus (3) allows the observer to look at the sample through a microscope while its temperature is increased. |
