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.

## Frequently asked questions

### Is the Surface tension: stalagmometer template free?

You can preview the Surface tension: stalagmometer template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates.

### Can I edit the Surface tension: stalagmometer template?

Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.

### Is the chemistry checked?

Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.

### Can I edit the glassware?

Yes. Every piece of glassware is a MolDraw apparatus object: move, resize, recolour the liquid or swap a piece and the joints stay connected.
