In Turkish: süzme, filtrasyon

How it is used

One of the most common lab steps. You filter a mixture or filter off a solid, by gravity filtration or by vacuum filtration with a Büchner funnel. The liquid that passes through is the filtrate; the solid left behind is the residue.

Example sentences

  1. Collect the crystals by vacuum filtration and wash them with cold solvent.

  2. After filtration, the filtrate was clear and colorless.

Common collocations

  • vacuum filtration
  • gravity filtration
  • filter paper
  • filter off
  • Büchner funnel
  • precipitateAn insoluble solid that forms when two solutions are mixed and separates out of the liquid. As a verb, the word means to form such a solid.
  • recrystallizationA purification method in which a solid is dissolved in a small amount of hot solvent and left to cool slowly, so that pure crystals form and impurities stay in solution.
  • centrifugeA machine that spins samples at high speed so that heavier particles or solids collect at the bottom of the tube and can be separated from the liquid.
  • distillationA method of separating or purifying liquids by boiling a mixture and cooling the vapor so that it condenses and is collected separately. It relies on differences in boiling point.
