1.1: Prelude to General Techniques
1.2: Glassware and Equipment
1.3: Transferring Methods
It is often needed to transfer chemicals from one container to another in organic chemistry laboratories. The proper approach to take depends on the nature of what needs to be transferred.
1.4: Heating and Cooling Methods
As reaction rate increases with temperature, it is very common to heat solutions in the organic laboratory. There are many heat sources available to the organic chemist, although some methods are better than others depending on the situation. Described in this section are some concepts that are common to all heating methods (e.g. how to boil controllably), followed by specifics on each heat source. Also included are methods used to cool solutions.
1.5: Filtering Methods
There are many methods used to separate a mixture containing a solid and liquid. If the solid settles well, the liquid can sometimes be poured off (decanted). If the solid has very small sized particles or forms a cloudy mixture, the mixture can sometimes be centrifuged or passed through a filter pipette (on the microscale, < 5 mL).
