Clamped column of silica between sand layers under the eluent, flow adapter on top worked by hand bellows, and fractions collected in test tubes in a rack. University / A-level extension.

## What the template shows

- Purify a mixture on silica gel, pushing the eluent through with gentle air pressure
- Flow adapter
- Its tap controls the pressure; open it to release
- Solvent mixture chosen by TLC (product Rf about 0.3); never let it fall below the sand
- Protects the top of the silica when solvent is added
- Silica gel
- Packed as a slurry over sand and a cotton plug; sample loaded in a narrow band at the top
- Collect in test tubes; check each by TLC and combine the pure ones
- Hand bellows
- Gentle pressure pushes eluent through at about 5 cm per minute
- Reaction setup

## Frequently asked questions

### Is the Flash column chromatography template free?

You can preview the Flash column chromatography 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 Flash column chromatography 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.
