Description
Funnel 55 mm with long stem, borosilicate glass is a laboratory funnel for controlled pouring and gravity filtration. Outer diameter is 55 mm, stem length 150 mm and stem outer diameter 6 mm, enabling smooth delivery into narrow-neck glassware and collection vessels. Fabricated from borosilicate glass, the funnel withstands typical chemical exposure and temperature changes encountered in analytical and preparative work. The elongated stem helps guide liquids during filtration with filter paper or simple transfer steps, reducing spillage and supporting tidy bench practice. Supplied as one piece from manufacturer Witeg, it is suited to analysis-funnel duties in teaching labs, research groups and quality-control environments. Net weight is 0,016 kg, so the item remains easy to position and store. Defined bowl and stem dimensions give a consistent geometry for routine sample preparation, solvent handling and filtrate collection. The long-stem format complements standard laboratory glassware without adding unnecessary bulk to the workspace.
