6 .3 .1 Sample preparation
In preparation, the boiling point tubes are filled with 5 to 10 mm of liquid sample. We recommend
using a syringe for simple filling. Insert a boiling point capillary into the boiling point tube with its open/
thick end down. Put the sample immediately into the heating block.
6 .3 .2 Determination without pre-registered boiling point method
• Choose the menu for boiling point determination.
• Make sure that all samples are removed.
• Press START to begin the determination process immediately with the last parameters used. They
are always saved in the instrument and are indicated in the green field in the lower part of the
screen.
If the current parameters do not meet your needs, press Edit and set the start temperature, stop
temperature, and temperature gradient.
