  • Transfer Pipette
    A plastic tool designed for moving small liquid volumes with minimal precision, commonly used for quick transfers in labs.
  • Burette
    A graduated glass tube with a stopcock, enabling precise delivery of liquid, essential for titrations and solution preparation.
  • Buckner Funnel
    A funnel with holes, used with vacuum filtration to separate solids from liquids by supporting filter paper.
  • Vacuum Flask
    A flask with a side arm for hose attachment, used to create suction and speed up filtration processes.
  • Graduated Cylinder
    A tall, marked container for measuring and transferring liquid volumes, offering moderate accuracy but not high precision.
  • Volumetric Flask
    A flask with a single calibration mark, used for making precise dilutions and preparing solutions to exact volumes.
  • Erlenmeyer Flask
    A conical flask ideal for mixing and transferring larger solution volumes, minimizing spillage due to its narrow neck.
  • Crucible
    A heat-resistant container with a lid, used to heat solids to high temperatures, often to remove water and obtain anhydrous samples.
  • Evaporating Dish
    A shallow ceramic vessel used to evaporate liquids, leaving behind solid residues after solvent removal.
  • Spatula
    A small, flat tool for transferring tiny amounts of powdered solids from containers to other vessels.
  • Scupula
    A larger, scoop-shaped instrument for moving greater quantities of solid materials, especially powders.
  • Funnel
    A conical device aiding in the transfer of liquids or fine solids into containers with narrow openings, reducing spillage.
  • Filter Paper
    A porous, folded membrane placed in funnels to separate solids (residue) from liquids (filtrate) during filtration.
  • Separatory Funnel
    A pear-shaped vessel with a stopcock, used for partitioning immiscible liquids or performing acid-base extractions.
  • Residue
    The solid material left behind on filter paper after filtration, separated from the liquid portion.
