Hi

guys,

I am assembling equipment for my hobby-perfumery lab and have a question about Disposable Pasteur

Pipettes:

Do essential oils affect pipettes made of Polyeten?
(If so, must I use pipettes of

glass?)

Could anyone shed a light on pipettes with a cotton "stopper"? How do I use them to suck up essential

oils into the pipette? The disposable polyeten pipettes have a integrated bulb, but the glass ones don't.
