SAFETY
Safety precautions
Before you work on the Melting point apparatus
- The block can be above 300 °C. Do not touch it and let it cool before cleaning.
- Glass capillaries are sharp; dispose of them in a sharps container.
- Some substances give off toxic vapours on melting; work in a ventilated area.
- Wear safety glasses when packing and handling capillaries.
