Used for filtering; the bottom of the frit is a porous glass surface, which allows material to be trapped. The ratings correspond to the pore sizes. There are other kind of funnels for filtration using filter papers. for pouring solids into a beaker or any container. Other kind of funnels can be used to pour liquid. for pouring liquid into a beaker. A funnel with a wide mouth is used for solids and is called powder funnel.

Used to hold round bottom flasks, to prevent them from rolling around and falling, and to keep them from touching the benchtop. This is used for starting a flame or often a bunsen burner. In general chemistry this is used to hold wire mesh to heat things on. This is used in all of the chemistries for measuring out small quantities of a substance relatively imprecisely.

Place the round bottom flask on an extenstion ring and clamp at the neck of the flask. Add a condenser to the vacuum adapter with a joint clip, being careful to steady the Condenser. Slide the open end of the condenser into the open end of the three-way adapter by carefully adjusting the clamps. Add an appropriately sized receiving flask by clamping it to the vacuum adapter with a joint clip.

Other kind of funnels can be used to pour liquid. Commonly used in filtering processes involving vacuum filtration, often with a buchner funnel or crucible funnel. The inlet may be connected to a vacuum source, such as a water aspirator. Classified as TC (to contain), test tubes are used to hold samples. Shown at left are several placed in a test tube rack. Commonly used to cover containers; also can be used for miscellan eous tasks

Provides reliable constant heating. These are often connected to a Variac, which regulates the amount of power comming into it, and so regulates the amount of heat going out. To store substances away from any moisture Used mainly for heating and also used for stirring solutions using stir bars It is mainly used as a power supply for heating mantles or other electrical equipment that require variable amounts of power.

While much of traditional chemistry teaching centers on multi-gram preparations, milligram of substances are sufficient for microscale chemistry. In universities, modern and expensive lab glassware is used and modern methods for detection and characterization of the produced substances are very common.
