The image displays two black and white icons of test tubes. The icon on the left is a simple representation of a test tube with a straight body and a flared opening at the top. The icon on the right is more detailed, showing a test tube with a series of horizontal ridges along its length, which are likely meant to represent the measurement markings on a real test tube. The background of the image is white, which contrasts with the black outlines of the icons. The style of the image is minimalistic and iconographic, commonly used in user interfaces or as symbols in various contexts.
