Thistle funnels are used to add small volumes of liquids to an exact position. A pipette (sometimes spelled pipet) is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser.

WebSeparatory Funnels. Separatory funnels are used in the lab for liquid-liquid extractions, separating a mixture's components into two solvent phases of different densities. The higher density liquid sinks to the bottom and can then be drained from a valve, leaving the less dense liquid in the funnel. Separatory funnels feature a stopcock at the ... WebIt is primarily used together with a Büchner funnel fitted through a drilled rubber bung or an elastomer adapter (a Büchner ring) at the neck on top of the flask for the filtration of samples. The Büchner funnel holds the sample isolated from the suction by a layer of filter paper. During filtration, the filtrate enters and is held by the ... WebSpecification. England. A/AS level.
