In general, a sieve separates wanted/desired elements from unwanted material using a tool such as a mesh, net or other filtration or distillation methods, but it is also used for classification of powders by particle size, or for size measurement as an analytical technique. The word "sift" derives from this term. A strainer is a type of sieve typically associated with separating liquids from solids.
