The image shows a simple line drawing of a beaker. The beaker has a flared opening at the top and a narrower opening at the bottom, which is typical for a flask. There are two circles on the side of the beaker, which could represent the flask's stopcock or a valve. The drawing is done in black ink on a white background. The style of the image is minimalistic and cartoonish, with clean lines and no shading or coloring.
