Pipette hand microtube open Illustration and Icon

Pipette hand microtube open. The illustration depicts a gloved operator using a mechanical micropipette to transfer liquid into an open microcentrifuge tube on a laboratory bench. In structural hierarchy, a disposable polymer pipette tip is mounted on an adjustable air‑displacement micropipette, and the tip is inserted into the mouth of a hinged‑cap microcentrifuge tube, which is held by the other gloved hand. Relevant fields include molecular biology, biochemistry, microbiology, and clinical laboratory science. Functionally, the apparatus enables precise microliter liquid handling for sample aliquoting, reagent mixing, and assay setup, including PCR (polymerase chain reaction) preparation. The entities shown are laboratory instrument and consumables rather than biological specimens. The site is a wet‑lab benchtop environment, and PPE (personal protective equipment) is evident as disposable gloves. Only hands are shown; no demographic details are provided.
