    Default Disposable Pasteur Pipettes?

    visit-red-300x50PNG
    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.

    Im no chemist, but while I

    took Chemistry in my undergraduate I prefered the glass pipettes. Oil will be a pain to get out of any pipette made

    of any material, so it will take quite some rinsing. However, the seperate bulb on the glass pipettes allows for

    more flexibility (in my opinion)

    In chemistry in high

    school (1970s), we didn't have squeeze bulbs for our pipettes. We would just suck on the end to draw the desired

    amount of fluid into the pipette, then place our finger over the top so the solution wouldn't spill out until we

    were ready to release it. I saw a chemist on TV just the other day using this technique, which surprised me as I

    thought it wasn't done anymore due to safety concerns.

    I personally use glass for

    everything I possibly can in perfuming. Otherwise you're googling for information on materials and solvents all

    day.
