How do you pick phenol?


Phenol comes in bottles as a hard solid chunk, and I need to take a few grams.
It is easy to melt, but how can I weight out? If I use a pipette, won't it solidify in it?
Any useful ideas would be appreciated!

Not if you heat it significantly above its melting point, use a pre-heated pipette, and work quickly. Another possible option is to pour a good amount of the molten stuff into a wide flat dish, like a baking dish, and let it solidify in there. Then break up the solid sheet.

I've transferred plenty of low melting solids by pipette just by heating them somewhat above the MP and then drawing them up and emptying them from the pipette rapidly a few times to heat it followed by finally taking my target quantity.

When the phenol is ripe, place a large sheet under the phenol tree and shake it vigorously. Make sure you're wearing a hat, so that you don't get any phenol falling on your head.

When in doubt, assume snark. But beware, lest it turn out to be a boojum.

Thanks for your nice ideas (and a joke. The Hunting of the Snark, are you talking about?)

I actually want a few batches for future projects, so making a solid sheet and crushing it might be a good way. If that fails, I'll try the pipette method.
