    Hot filtration, solution contained in the Erlenmeyer flask is heated on a hot plate to prevent re-crystallization of solids in the flask itself. There are several laboratory filtration techniques depending on the desired outcome namely, hot, cold and vacuum filtration. Some of the major purposes of obtaining the desired outcome are, for the ...

    These systems are compact and possess a sturdy design, Compared to cross-flow filtration, plate and frame configurations possess a reduced capital expenditure; however the operating costs will be higher. The uses of plate and frame modules are most applicable for smaller and simpler scale applications (laboratory) which filter dilute solutions ...

    The process thus in its essence is similar to distillation, however the material which is condensed on the cooler surface then has to be removed mechanically, thus requiring different laboratory equipment. Bioleaching is the extraction of metals from their ores through the use of living organisms. Separation process. From Crystallization

  5. Filter funnel - Wikipedia

    en.wikipedia.org/wiki/Filter_funnel

    A filter funnel is a laboratory funnel used for separating solids from liquids via the laboratory process of filtering. [1] In order to achieve this, a cone-like shaped piece of filter paper is usually folded into a cone and placed within the funnel. The suspension of solid and liquid is then poured through the funnel.

    A vacuum tight seal and stability of the Büchner flask and filter are essential during the filtration process. A Büchner ring can be used with Büchner funnels, flasks, glass crucibles and Gooch crucibles. The wide flange and large surface contact ensures an excellent vacuum tight seal whilst the rings are easy to remove and offer excellent ...

  7. Purified water - Wikipedia

    en.wikipedia.org/wiki/Purified_water

    Distilled water is produced by a process of distillation. [1] Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water. [2] A white or yellowish mineral scale is left in the distillation apparatus, which requires regular cleaning.
