Blood graduated glass bottle

Old laboratory or hospital graduated glass jar. Was used for blood transfusions (etched) I bought it like a lot of pieces for sale here in an old hospital that was closing its doors in rio de janeiro, brazil. These pots were used to decorate. Besides marriage and put plants, flowers, we had a good hundred of several sizes and colors, very pretty. This one is very rare. 500ml. 18x8cms.
