Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. [1]
Recrystallization: In analytical and synthetic chemistry work, purchased reagents of doubtful purity may be recrystallised, e.g. dissolved in a very pure solvent, and then crystallized, and the crystals recovered, in order to improve and/or verify their purity.
By cooling the reaction mixture to room temperature, crystals of the porphyrin precipitate, and are collected by filtration on a Büchner filter as illustrated by the photograph here beside: [9] Precipitation may also occur when an antisolvent (a solvent in which the product is insoluble) is added, drastically reducing the solubility of the ...
Filter (chemistry), a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass Filter (aquarium), critical components of both freshwater and marine aquaria; Filter paper, a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine solids ...
Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular (10 3 –10 6 Da ) solutions, especially protein ...
Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine solid particles from liquids or gases. Filter paper: used for separating solid from liquid. The raw materials are typically different paper pulps. The pulp may be made from softwood, hardwood, fiber crops, or mineral fibers.
Amid controversy surrounding the carnivore diet, researcher Nick Norwitz recently released a video in which he debunks eight myths surrounding the meat-heavy eating plan.
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.
