Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
Stalagmometer clamped vertically with a pipette filler, drops counted into a beaker, density from a pycnometer. University physical; IB / A-level extension.
What the template shows
- Count the drops a fixed volume forms and compare with water
- Drops collected
- Or weigh them: mass per drop ∝ surface tension
- Pipette filler
- Draw the liquid above the upper mark
- Bulb between two marks
- Count the drops as the level falls from the upper to the lower mark
- Flat-ground tip
- Clean and grease-free; drops must form slowly, not stream
- Gives the density ρ. γ = γ(water) × n(water)ρ / nρ(water); γ(water) = 72.0 mN m⁻¹ at 25 °C
- Reaction setup
Drawn with 13 shapes – every one editable in MolDraw.
