For dipping I use a small pill bottle as I get them from my wife and father (they take a lot of pills)
That way you can use it and reuse it until it goes bad.
Also heating up the part works.
For dipping pots I use shot glasses
And chemistary evaporating dish.
And a rather large coffe mug I bought a dollar store.
