    Hi Aurora
    I am looking at the shopping list and will list what I do not have on hand. Bromothymol blue, PTC paper, liquid crystal thermometer strip, goldenrod paper and the blue highlighted parts for the working lung model. Are these considered the hard-to-find pieces you will send to us when requested ?

  3. Which specific parts are you having trouble finding?

  4. Jennie Luh says:

    Hi Aurora,
    Just wondering if there’s hard-to-find pieces that I could request for unit 19. Please let me know if this is the correct place to put in a request for them or do I have to purchase them on-line?
