The image displays a laboratory workstation in Recife, Brazil, featuring an arrangement of glass test tubes and pipettes on a light-colored wooden surface. A prominent white styrofoam rack, designed for holding test tubes, occupies the central and right portions of the frame. The upper section of this rack contains approximately 60-70 empty, clear glass test tubes, uniformly upright. The lower, foreground section of the rack holds 20-25 test tubes, many of which contain varying volumes of liquids exhibiting yellow, light yellow, orange, and reddish-pink coloration, consistent with biological samples such as plasma. Several of these test tubes bear small red and white adhesive labels; "Plasma" is partially legible on one label. On the left side of the wooden surface, two manual micropipettes are positioned. One is a dark blue model with a white tip ejector and a visible black adjustment knob. The second, partially visible, is blue and white with the serial number "225215" printed on its body. In the upper left background, a yellow rack filled with numerous small yellow pipette tips is visible, adjacent to a partially obscured white styrofoam container. A small white plastic cap and a crumpled fragment of white material lie on the wooden surface near the pipettes. The bottom right edge of the styrofoam rack exhibits distinct purple and black marker scribbles. No personnel are visible in the scene.
