Paper chromatography kit:
Paper chromatography (PC) is performed by 1000's of pupils each year BUT the standard method gives really BAD results.
We have developed a low cost, simple to use PC kit for the separation of black food dye, that is highly reproducible and actually works! - measure real Rf values.
Each kit can be used by class size of up to 30 x GCSE pupils - each performing individual experiments. Also, with spare consumables to perform the experiment 5 times.

Column chromatography kit:
The same black food dye sample can be separated using a mini Column Chromatography (CC) method.
Fully aqueous conditions (no organic solvents) hence can be used on the open bench.  Each different coloured dye can be separated and collected.
