Preparing your own thin layer chromatography plates (and then using them)

Step 4 Suspend the powder in water

Transfer the powder into an old plastic bottle that you will never want to use for anything else again (especially if you let the plaster set before cleaning it out and are as lazy as I).

Add 10mL water (or a water to powder ratio of 2:1), the syringe is handy for this.

Cap the bottle and shake violently for one minute, the bottle that is. The goal is to form a slurry of all the solid in water.
