A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.

Mammography images are created by the process of x-rays passing through breast tissue and interacting with a digital detector. The anode in the x-ray tube used for mammography is made of molybdenum, or rhodium, rather than tungsten which is commonly used in general x-ray tubes. For more information about x-ray formation see the previous section (X-rays).
