  2. Dropping funnel - Wikipedia

    en.wikipedia.org/wiki/Dropping_funnel

    Pressure-equalizing dropping funnels have an additional narrow-bore glass tube from the bulb of the funnel, to the ground glass joint around the stem. These replace the liquid volume lost in the bulb with the equivalent gas volume from the flask into which the reagent is flowing, and are useful when handling air-sensitive reagents in a sealed ...

    Acidbase extraction is a subclass of liquid–liquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [2] and results in the product being largely free of acidic or basic impurities.

    POU water dispensers are connected to a water supply, while bottled water dispensers require delivery (or self-pick-up) of water in large bottles from vendors. Bottled water dispensers can be top-mounted or bottom-loaded, depending on the design of the model. Bottled water dispensers typically use 11- or 22-liter (5- or 10-gallon) dispensers ...

  9. Büchner flask - Wikipedia

    en.wikipedia.org/wiki/Büchner_flask

    It 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 ...
